The study of the catalyst nature effect on the catalytic olefination of 4-chlorobenzaldehyde hydrazone by polyhaloalkanes revealed that the best catalysts for the reaction are copper salts. With polyhaloalkanes more active than CCl4, like CBrs

We report a tandem approach to synthesize symmetrical azines from alcohols and hydrazine hydrate catalyzed by synthesized arene Ru(II) complexes of aroylthiourea ligand. Notably, the catalytic efficiencies of six- and four-membered N,S-chelate ruthenium c

A controlled tandem synthetic route to azines from various alcohols and hydrazine hydrate by the use of a Ni(II) complex of 2,6-bis(phenylazo)pyridine as a catalyst is reported. In marked contrast to the previous report, the reaction is operative using an earth-abundant metal catalyst, milder reaction conditions, and aerobic conditions, which though are desirable but unprecedented in the literature. The catalytic reaction has a vast substrate scope including a single-step synthesis of phthalazine from 1,2-benzenedimethanol and hydrazine hydrate via intramolecular coupling. Mechanistic investigation suggests that the coordinated ligand redox controls the reaction by the use of a reversible azo (N=N)/ hydrazo (NH - NH) redox couple where the metal center is used primarily as a template.
