Ligand-Assisted Nickel Catalysis Enabling N, N-Dialkylation and Cyclization of Acyl Hydrazides Using Aliphatic Alcohols Herein we describe a nickel-catalyzed catalytic N,N-dilakylation protocol for acyl hydrazides. A series of aliphatic alcohols and diols were successfully dehydrogenated and used for this challenging dialkylation as well as some cyclization reactions.

Photochemical dehydrogenative transformation to heterocycles facilitated by an azo/hydrazo redox couple† Despite the rich redox chemistry available for the azo motif, studies on its photochemical activation and subsequent application in catalysis are scarce. We design a small organic molecule, benzothiazole azo β-naphthol, which can be reduced under very mild reaction conditions upon photoexcitation.
