Complex OsH6((PPr3)-Pr-i)(2) is an efficient catalyst precursor for the addition of pinacolborane and catecholborane to the C-N triple bond of alkyl nitrites. In this way, a variety of N,N-diborylamines have been isolated and fully characterized, including 13 derivatives not described so far. The range of nitrites used is wide and comprises substrates having unfunctionalized linear and branched chains, and functionalized chains with methoxide, trifluoromethyl, aryl, pyridyl, benzoyl, or cyanide groups. Kinetic studies demonstrate that the overall process consists of two consecutive irreversible reactions: the catalytic metal-promoted monohydroboration of the nitrile to afford the borylimine and the metal-free stoichiometric hydroboration of the latter to give the diborylamine. The mechanism of the hydroboration has been established by combining the kinetic analysis of the catalysis, stoichiometric reactions, and DFT calculations. The rate-determining step of the catalysis is the insertion of the C-N triple bond of the nitrite into the Os-B bond of an osmium-sigma-borane intermediate and is regiodirected by the nucleophilicity of the nitrogen atom and the electrophilicity of the carbon atom of the nitrite.

Switchable selective hydrogenation among the groups in multifunctional compounds is challenging because selective hydrogenation is of great interest in the synthesis of fine chemicals and pharmaceuticals as a result of the importance of key intermediates. Herein, we report a new approach to highly selectively (>99%) reducing C=X (X = O, N) over the thermodynamically more favorable nitro groups locating the substrate in a metal-organic capsule containing NADH active sites. Within the capsule, the NADH active sites reduce the double bonds via a typical 2e(-) hydride transfer hydrogenation, and the formed excited-state NAD(+) mimics oxidize the reductant via two consecutive 1e(-) processes to regenerate the NADH active sites under illumination. Outside the capsule, nitro groups are highly selectively reduced through a typical 1e(-) hydrogenation. By combining photoinduced 1e(-) transfer regeneration outside the cage, both 1e(-) and 2e(-) hydrogenation can be switched controllably by varying the concentrations of the substrates and the redox potential of electron donors. This promising alternative approach, which could proceed under mild reaction conditions and use easy-to-handle hydrogen donors with enhanced high selectivity toward different groups, is based on the localization and differentiation of the 2e(-) and 1e(-) hydrogenation pathways inside and outside the capsules, provides a deep comprehension of photocatalytic microscopic reaction processes, and will allow the design and optimization of catalysts. We demonstrate the advantage of this method over typical hydrogenation that involves specific activation via well-modified catalytic sites and present results on the high, well-controlled, and switchable selectivity for the hydrogenation of a variety of substituted and bifunctional aldehydes, ketones, and imines.

Herein, we present a robust and eco-friendly dynamic kinetic resolution (DKR) protocol for secondary alcohols using a combined heterogeneous catalytic CAL-B/VOSO4 system at 50 degrees C in the relatively green solvent heptane. This catalytic system is active and chemo- and enantioselective for up to 5 cycles. A set of 13 aromatic and heteroaromatic secondary alcohols were evaluated to determine the substrate scope. The performance of the combined CAL-B/VOSO4 system was improved by employing a low-cost, homemade Teflon tube to compartmentalize the catalysts in one-pot conditions, making this system for up to 8 reaction cycles.

In the field of catalysis, material scientists pay much attention to tuning the activity and chemoselectivity of metal nanoparticles. Herein, we design and successfully synthesize a series of Co NPs which show high performance on hydrogenation of nitroarenes with both activity and chemoselectivity. Co-0.15@C/PC preferentially activates the -C=O bond over -NO2 in water with ammonia borane (AB); however, when the hydrogen source is changes to hydrazine hydrate (HH), the results are the opposite. The Co-based catalyst exhibits exceptionally high catalytic activity (with a TOF value of 10512 h(-1), which is approximately 100 times than the akin catalysts) and chemo-selectivity for the hydrogenation of nitro compounds under mild conditions. Additionally, the catalyst can be separated easily by a magnet and shows prominent stabilit, which means that it can be reused for at least 10 cycles.

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.

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.
