Cobalt-Catalyzed Hydrohydrazination of Dienes and Enynes:  Access to Allylic and Propargylic Hydrazides

Abstract

[reaction: see text] The cobalt-catalyzed hydrohydrazination reaction of dienes and enynes is presented. Allylic and propargylic hydrazines were obtained in synthetically useful yields (allylic amines, 60-90%; propargylic amines, 47-83%) and good chemo- and regioselectivity.
