Aqueous titanium trichloride reductively removes cyano and halo groups from the correspondingly substituted pyridines by a two electron-transfer process and promotes reduction of pyridyl-ketones and aldehydes to glycols by one electron-transfer process under very simple experimental conditions.

A paired electrochemical method for paralleling benzylic bromination of alkylarenes under irradiation with reductive pinacol coupling in a divided cell has been developed. A variety of benzyl bromides at the anode and pinacols at the cathode were obtained simultaneously in moderate-to-high faradaic efficiency. This parallel paired electrochemical protocol showed a broad substrate scope and high chemoselectivity

Electrochemical pinacol coupling of aromatic carbonyl compounds in a [BMIM][BF4]–H2O mixture
aromatic carbonylcompounds were carried out using an 80% [BMIM][BF4]–H2O mixture as the electrolytic medium. The corresponding diols were obtained in good to excellent yields with moderate diastereoselectivity. The stereoselectivity can be explained using the strongly-bound ion-pairs formed between the imidazolium cation and the radical anions of the carbonylcompounds. The ionicliquid replaces both
