Benzylic alcohols have an important role in organic synthesis as target molecules of biological interest, which can be produced from the reduction of aromatic carbonyl substrates. In this work, the sonoelectrocatalytic hydrogenation (SECH) of aryl ketones was studied in water. The ultrasonic irradiation was carried out at frequency of 20 kHz +/- 500 Hz with a cylindrical titanium probe (MS 73 microtip; Ti-6AI-4V alloy; 3.0 mm diameter; Pacoustic- = 2.11 W). The results showed that the ultrasound irradiation enhances the mass-transport of the substrates from the bulk solution to the electrode surface, increasing the substrate availability to react with the adsorbed H, leading to higher yields. Regarding the electrode material, the following hydrogenation yields of a group of acetophenones was observed: Cu (79.0 +/- 1.5%) > Ni (73.0 +/- 2.0%) approximate to Fe/Ni (72.0 +/- 1.7%) > graphite (69.0 +/- 1.7%) > Fe (67.5 +/- 2.3%). The SECH presented a slight variation in the reactivity of some reagents, and its behaviour depends on the catalytic nature of the electrode support. Besides the lower overpotential and higher exchange current density of the graphite, it was surprisingly active under ultrasound irradiation, showing higher yields and current efficiencies than others electrocatalytic hydrogenation (ECH) procedures. The ultrasound irradiation decreases more than 6-folds the energy consumption of the ECH method, making it an effective and inexpensive way to produce alcohols from the respective aryl ketones in water.

Developing efficient and selective strategies to approach complex architectures containing (multi)stereogenic centers has been a long-standing synthetic challenge in both academia and industry. Catalytic cascade reactions represent a powerful means of rapidly leveraging molecular complexity from simple feedstocks. Unfortunately, carrying out cascade Heck-type reactions involving unactivated (tertiary) alkyl halides remains an unmet challenge owing to unavoidable beta-hydride elimination. Herein, we show that a modular, practical, and general palladium-catalyzed, radical three-component coupling can indeed overcome the aforementioned limitations through an interrupted Heck/allylic substitution sequence mediated by visible light. Selective 1,4-difunctionalization of unactivated 1,3-dienes, such as butadiene, has been achieved by employing different commercially available nitrogen-, oxygen-, sulfur-, or carbon-based nucleophiles and unactivated alkyl bromides (>130 examples, mostly >95:5 E/Z, >20:1 a). Sequential C(sp(3))-C(sp(3)) and C-X (N, O, S) bonds have been constructed efficiently with a broad scope and high functional group tolerance. The flexibility and versatility of the strategy have been illustrated in a gram-scale reaction and streamlined syntheses of complex ether, sulfone, and tertiary amine products, some of which would be difficult to access via currently established methods.

The asymmetric direct reductive amination of prochiral ketones with aryl amines using 1-hydrosilatrane with a chiral Bronsted acid catalyst is reported. This is the first known example of chiral Bronsted acid-catalyzed asymmetric reductive amination using a silane as the hydride source. The reaction features a highly practical reducing reagent and proceeds efficiently at room temperature without a specialized reaction setup or equipment to exclude air or moisture. This method provides high conversion and enantiomeric excess up to 84% of the desired chiral secondary amines with minimal side products.

A new Au(I)-catalyzed method for the preparation of trisubstituted indolizines from easily accessible 2-propargyloxy-pyridines is reported. The reaction tolerates a wide range of functionality, allowing for diversity to be introduced in four distinct regions of the product (R, R-1, R-2, and Ar). The proposed mechanism proceeds via enol addition to an allenamide intermediate and explains the observed increase in yields when electron poor methyl ketones are utilized.

An efficient [4+1C](insert) approach to the coupling of enaminones with donor/acceptor or donor/donor carbenes by the AgOTf-catalyzed C-C bond carbenoid formal insertion/cyclization/[1,5]-shift cascade reaction was successfully developed, providing distinct chemo- and regioselective multisubstituted pyrroles. The plausible reaction mechanism involves two catalytic cycles: in the first one, silver ions regioselectively catalyze the C-C bond formal insertion reaction; in the second one, silver ions chemo- and regioselectively control the cyclization and [1,5]-shift reactions. This method not only provides convenience and applies atom economy in the synthesis of multisubstituted pyrroles but also presents an entry point for further pyrrole diversification via facile modification of resulting 4H-pyrrole products, as displayed by a short formal synthesis of the natural product lamellarin L.

A new rhodium(III)-triphenylphosphine mixed ligand complex, [Rh(PPh3)(L)Cl-2] (1) is synthesized by benzylic C-S bond cleavage of L-CH2Ph ligand (where, L-CH2Ph = 2-(benzylthio)-N-(pyridin-2-ylmethylene)aniline). The complex is thoroughly characterized by several spectroscopic techniques. Geometry of the complex is confirmed by single crystal X-ray crystallography. Electronic structure, redox properties, absorption and emission properties of the complex were studied. DFT and TDDFT calculations were carried out to interpret the electronic structure and absorption properties of the complex respectively.

An efficient additive-free manganese-catalyzed hydrogenation of nitriles to primary amines with molecular hydrogen is described. The pre-catalyst, a well-defined bench-stable alkyl bisphosphine Mn(I) complex fac-[Mn(dpre)(CO)(3)(CH3)] (dpre=1,2-bis(di-n-propylphosphino)ethane), undergoes CO migratory insertion into the manganese-alkyl bond to form acyl complexes which upon hydrogenolysis yields the active coordinatively unsaturated Mn(I) hydride catalyst [Mn(dpre)(CO)(2)(H)]. A range of aromatic and aliphatic nitriles were efficiently and selectively converted into primary amines in good to excellent yields. The hydrogenation of nitriles proceeds at 100 degrees C with a catalyst loading of 2 mol % and a hydrogen pressure of 50 bar. Mechanistic insights are provided by means of DFT calculations.

Enantiopure secondary alcohols are fundamental high-value synthetic building blocks. One of the most attractive ways to get access to this compound class is the catalytic hydroboration. We describe a new concept for this reaction type that allowed for exceptional catalytic turnover numbers (up to 15 400), which were increased by around 1.5-3 orders of magnitude compared to the most active catalysts previously reported. In our concept an aprotic ammonium halide moiety cooperates with an oxophilic Lewis acid within the same catalyst molecule. Control experiments reveal that both catalytic centers are essential for the observed activity. Kinetic, spectroscopic and computational studies show that the hydride transfer is rate limiting and proceeds via a concerted mechanism, in which hydride at Boron is continuously displaced by iodide, reminiscent to an S(N)2 reaction. The catalyst, which is accessible in high yields in few steps, was found to be stable during catalysis, readily recyclable and could be reused 10 times still efficiently working.

Traditional cross-coupling reactions show some disadvantages like the use of organohalides or the production of stoichiometric amounts of waste. The dehydrative homo- or heterocoupling of alcohols therefore arises as an interesting approach for a highly atom-economical formation of carbon-carbon bonds, since water is produced as the only by-product. We herein report a simple and direct, metal-free protocol for the synthesis of olefins by applying catalytic amounts of a sulfonic acid and triphenylphosphane under air. A variety of olefins could be synthesized from benzylic alcohols under relatively mild conditions. Additionally, dehydrative hydroarylation of benzylic alcohols with electron-rich arenes was possible by using only Bronsted acid under otherwise same reaction conditions. We could show that phosphane additives are essential to overcome oligomerization as main side reaction by the occupancy of the reactive carbocation intermediate.

A bifunctional 3d-metal catalyst for the cascade synthesis of diverse pyrroles from nitroarenes is presented. The optimal catalytic system Co/NGr-C@SiO2-L is obtained by pyrolysis of a cobalt-impregnated composite followed by subsequent selective leaching. In the presence of this material, (transfer) hydrogenation of easily available nitroarenes and subsequent Paal-Knorr/Clauson-Kass condensation provides >40 pyrroles in good to high yields using dihydrogen, formic acid, or a CO/H2O mixture (WGSR conditions) as reductant. In addition to the favorable step economy, this straightforward domino process does not require any solvents or external co-catalysts. The general synthetic utility of this methodology was demonstrated on a variety of functionalized substrates including the preparation of biologically active and pharmaceutically relevant compounds, for example, (+)-Isamoltane.
