In order to introduce the concept of covalent organic frameworks (COFs), an important class of predictable crystalline porous polymers, an integrated laboratory experiment for advanced organic chemistry students is reported. The importance of these kind of polymers and their multiple applications are presented as a part of key concepts in polymer and organic chemistry, bridging these disciplines to materials science. Students carry out the synthesis and characterization of an imine-linked COF and its building blocks. The polymer is formed at room temperature by using solvent-assisted synthesis and mechanochemistry. Students are trained in solid state characterization techniques, including FTIR spectroscopy, thermogravimetric analysis (TGA), C-13 NMR cross-polarization-magic angle spinning (CP-MAS) NMR spectroscopy, and powder X-ray diffraction (PXRD), which are essential in the important field of reticular chemistry. Therefore, this lab experience constitutes a practical introduction to COFs.

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.

The iridium complex1based on a metalated CNP ligand containing an imidazolin-2-ylidene fragment has been prepared by treatment of the ligand precursor4with Ag2O followed by reaction with [IrCl(COE)(2)](2). The chlorohydride imidazolidin-2-ylidene complex6, which is isostructural to1, was synthetized by reaction of the previously reported dihydride derivative3with CH2Cl2. Complexes1and6exhibit luminescence arising from a(3)MLCT/ILCT state involving the metalated CNP ligand, which is particularly intense for1in the solid state at 298 K. Furthermore, the reactivity of complexes1and6towards bases was compared. Deprotonation of1with KOtBu produced the selective formation of the dinuclear complex7; meanwhile, the reaction of6led to a complex mixture of products. The same reactions carried out in the presence of PPh(3)produced the selective deprotonation of the P-bonded methylene bridges of1and6, yielding the isostructural derivatives9and10. DFT calculations performed on theuNHC-containing tautomersIandII, and thesNHC-based isomersIIIandIV, showed that the NHC-deprotonated derivativesIIandIVare more stable by 3.20 and 2.73 kcal mol(-1), respectively, than their P-deprotonated counterparts (IandIII). However, a reverse stability order was observed for hexacoordinated tautomersI center dot LandII center dot L, andIII center dot LandIV center dot L(L = PPh3, CO, MeCN). Finally, the catalytic activity of complex3in the transfer hydrogenation of ketones has been assessed.

A family of hemi-salen (L1H-L6H) and hemi-salan (L1aH-L2aH) ligands-based N,O-chelated binuclear boron-fluoride [L-n(BF2)(2)] (n = L-1-L-6 or L-1a-L-2a) complexes have been prepared and characterized by a variety of spectroscopic techniques (H-1, C-13 and F-19 NMR, FT-IR, UV-Vis, LC-MS, and fluorescence spectra) and elemental analysis. All of the binuclear boron-fluoride complexes exhibit strong absorption bands due to S-0 -> S-1 transitions and strong fluorescence properties were observed at room temperature in the solution. The binuclear boron complexes containing two naphthyl groups are significantly red-shifted in comparison with the other binuclear boron-fluoride complexes. After the structures are characterized, these hemi-salen and salan ligand-based N, O-chelated binuclear boron-fluoride complexes were utilized to the transfer hydrogenation of the different acetophenone derivatives conversion to 1-phenylethanol derivatives as catalysts.

Elemental sulfur, as a by-product of petroleum refining, is regarded as a solid waste stored in above-ground deposits due to limited existing applications, meanwhile, mercury contamination is one of the current environmental issues considering its high toxicity to the human, and how to safely dispose of hazardous waste adsorbents is still an unavoidable problem. This study addresses these need by utilizing sulfur for preparation of a polysulfide complex material to capture Hg(II) and convert the Hg(II)-containing spent adsorbent into a catalyst. Initially, the mesoporous silica was prepared and functionalized by using diatomite and APTES, then, an in-situ preparation method was applied to obtain the amine-mesoporous silica/poly(m-aminothiophenol) nanocomposite (MAP), subsequently sulfur was copolymerized with MAP and vinylic-potato starch through inverse vulcanization, forming the sulfur crosslinked polymers composite cp(MAP-S-PS). Many characterizations were employed to determine the physicochemical structure andmorphology of cp(MAP-S-PS). The adsorption study showed the cp(MAP-S-PS) exhibited the theoretical maximum adsorption capacity of 436.68 mg/g, good regeneration performance after 5 cycles and excellent selectivity between Hg(II) ions and common cations. Furthermore, the collected spent adsorbent cp (MAP-S-PS)/Hg(II) was reused as a catalyst for synthesis of acetophenone with 89% yield, and most of phenylacetylene derivatives were also transformed to corresponding acetophenone in good yields.

Site-specific functionalization of sp3 C-H bonds adjacent to a nitrogen atom is one of the unexplored heterogeneous transformations. Aiming at alpha-arylation of glycine derivative for rapid access to indolylglycines without the aid of bases, a chemically robust and two-dimensional COF is prepared. Integration of [2,2 ‘]bipyridyl (Bpy) unit benefits active homogeneous complex Ru(Bpy)22+ to anchor over the framework backbone to devise Ru-COF that acts as unprecedented visible light photocatalyst towards cross-dehydrogenative coupling of secondary amines with indoles in excellent yield at room temperature, under aerobic condition. Ru-COF shows admirable reusability and superior activity to that of Ru(Bpy)3Cl2, while substrate variation studies delineate wide ranges of functional group tolerance. To the best of Ru-COF, atom-economic C-H functionalization is realized as iminium ion is in situ generated. The photocatalytic route is detailed from astute modulation of optical band-gap in light of density-functional theory studies and experimental results, which validates single-electron-transfer pathway.
