Synthesis of Butyrolactones by Nickel‐Catalyzed Reductive Cyanation of Alkynols in Water.

Abstract

A novel catalytic synthesis of butyrolactones is studied. It is suggested that the reaction is catalyzed by a cyanonickel(II) species, which is regenerated via its oxidation with water. -(GARCIA GUTIERREZ*, J. L.; JIMENEZ-CRUZ, F.; ESPINOSA, N.
