CAN-mediated oxidation of electron-deficient aryl and heteroaryl hydrazines and hydirazides

Aryl and heteroaryl hydrazines and hydrazides were successfully oxidised using CAN, deriving dehydrazinated products. The reaction pathway strongly depends on the nature of the substrate, resulting in the formation of hydrocarbons or alkoxy derivatives. When deuterated solvents such as methanol-d(4) or acetonitrile-d(3) were used, a regiospecific incorporation of deuterium was achieved.
