An efficient Ni-catalyzed reductive carboxylation of brached and linear allylic alcohols with CO2 provides linear β,γ-unsaturated carboxylic acids as the sole regioisomer with generally high E/Z stereoselectivity. In addition, the carboxylic acids can be generated from propargylic alcohols via a hydrogenation step made possible by a Ni hydride intermediate produced by a hydrogen atom transfer from water.
