A practical procedure for the addition of arylboronic acids to aromatic aldehydes has been developed in the presence of NiCl2(PPh3)2/1,3-bis-(2,6-diisopropylphenyl)imidazolium chloride (IPr·HCl) system with good yield. Generally, electron-rich and-neutral aryl aldehydes showed excellent reactivity and provided desired products in high yields. This procedure will provide new way to the synthesis of diarylmethanols.

A bench-stable combination of NaBH4-acetylacetone was developed for the efficient chemoselective reduction of aldehydes in the presence of ketones. This method offers a useful synthetic protocol for distinguishing carbonyl reaction sites, and its synthetic utility is reflected by its moisture tolerance and high efficiency in a variety of complex settings.
An Efficient Ga(OTf)3/Isopropanol Catalytic System for Direct Reduction of Benzylic Alcohols

This study aims to report the first gallium-catalyzed direct reduction of benzylic alcohols using isopropanol as a reductant. The reaction proceeds via gallium catalyst-assisted hydride transfer of the in situ-generated benzylic isopropyl ether. The method generates only water and acetone as byproducts and thus provides an atom-economic and environmentally friendly approach to the synthesis of di- and triarylmethanes, which are important substructures in various bioactive compounds and functional materials.
