Nitrogen–nitrogen multiple bond cleavage and reduction in diphenyldiazomethane and azobenzene by a titanium (III) complex

Abstract

Diphenyldiazomethane reacted with [cpTiCl₂]_n(cp =η=η⁵-C₅H₅) forming a dinuclear complex, [(cpTiCl)₂(µ-Ph₂CN₂)₂], in which two titanium atoms are doubly bridged by a hydrazzonido (2–) ligand; a related dimeric complex containing the (cpTiCl) unit bridged by both a hydrazo (2–) and a phenylnitrene ligand, [(cpTiCl)₂(µ-PhN)(µ-Ph₂N₂)], was formed from the reaction of [cpTiCl₂]_n with azobenzene.
