Chitosan microspheres modified by 2-pyridinecarboxaldehyde were prepared and used in the construction of a heterogeneous catalyst loaded with nano-Cu prepared by a reduction reaction. The chemical structure of the catalyst was investigated by Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and X-ray Photoelectron Spectroscopy (XPS). Under mild conditions, such as no ligand at room temperature, the catalyst was successfully applied to catalyze the borylation of alpha,beta-unsaturated receptors in a water-methanol medium, yielding 17%-100% of the corresponding beta-hydroxy product. Even after repeated use five times, the catalyst still exhibited excellent catalytic activity.

A diboron-mediated rhodium-catalysed transfer hydrogenation system using water as the hydrogen donor is developed. In addition to a series of alkenes with good functional group tolerance, this rhodium-based catalytic system also effectively reduces aldehydes and ketones. A plausible mechanism involving the Rh-I-catalysed hydrogen generation and Rh-0-catalysed hydrogenation is proposed for the reaction.

Efficient chemoselective transfer hydrogenation of the C=C bond of alpha,beta-unsaturated ketones has been developed, using the iridium complexes containing pyridine-imidazolidinyl ligands as catalysts and formic acid as a hydrogen source. In comparison with organic solvents or H2O as solvent, the mixed solvents of H2O and MeOH are critical for a high catalytic chemoselective transformation. This chemoselective transfer hydrogenation can be carried out in air, which is operationally simple, allowing a wide variety of alpha,beta-unsaturated substrates with different functional groups (electron-donating and electron-withdrawing substituents) leading to chemoselective transfer hydrogenation in excellent yields. The practical application of this protocol is demonstrated by a gram-scale transformation.

A generalized, simple and efficient transfer hydrogenation of unsaturated bonds has been developed using HBP in and various proton reagents as hydrogen sources. The substrates, including alkenes, alkynes, aromatic heterocycles, aldehydes, ketones, imines, azo, nitro, epoxy and nitrile compounds, are all applied to this catalytic system. Various groups, which cannot survive under the Pd/C/H-2 combination, are tolerated. The activity of the reactants was studied and the trends are as follows:styrene>diphenylmethanimine>benzaldehyde>azobenzene>nitrobenzene>quinoline>acetophenone>benzonitrile. Substrates bearing two or more different unsaturated bonds were also investigated and transfer hydrogenation occurred with excellent chemoselectivity. Nano-palladium catalystin situgenerated from Pd(OAc)(2) and HBP in extremely improved the TH efficiency. Furthermore, chemoselective anti-Markovnikov hydrodeuteration of terminal aromatic olefins was achieved using D2O and HBP in via in situ HD generation and discrimination.

A palladium-catalyzed oxidative cascade reaction of alpha-tosylamide allenes has been developed. The reactivity of the allenes is controlled by the tosylamide group. In the presence of terminal alkynes the reaction proceeds via a pathway leading to a one-pot construction of pyrrole rings. Moreover, a solvent-controlled chemoselectivity of the cascade reaction was realized, leading to a stereospecific and divergent synthesis of (Z)-tetrasubstituted olefins, 2,5-dihydropyrroles, and pyrroles. Enantioenriched (Z)-tetrasubstituted olefins and 2,5-dihydropyrroles are readily synthesized by chirality transfer using this approach.

A highly efficient rongalite-mediated three-component radical annulation reaction to furnish fully substituted pyrazoles from aryldiazonium salts and alpha,beta-unsaturated aldehydes or ketones under metal- and oxidant-free conditions at room temperature has been developed. In this transformation, aryldiazonium salts served as the precursor of both the aryl and aryl hydrazine units. Mechanistic investigations indicated that rongalite could act as a radical initiator and reducing reagent simultaneously in the reaction.
