Cu(II)/TBAI-catalyzed esterification of acid hydrazides via C(sp3)-H oxidative coupling

Article abstract of DOI:10.1055/s-0034-1379478

A Cu²⁺/TBAI-cocatalyzed allylic ester synthesis was developed, which allows a direct coupling of acid hydrazides and cycloalkanes. This process makes use of commercially available, inexpensive, and abundant starting materials. Based on the extensive experimental data, a plausible radical mechanism was suggested.
