Stable palladium–carbon σ bonded complex obtained by reaction of acrylonitrile with palladium acetate

Abstract

Palladium acetate reacts with acrylonitrile to give a 1:2 mixture of (E)- and (Z)-MeCO₂CHCHCN as the final product; reaction in 1,2-dichloroethane at room temperature gives a stable organopalladium compound, which has been characterized as Pd(MeCO₂)₂(CHCHCN) by X-ray crystrallography, and represents the first example of an acetoxypalladium intermediate isolated in the absence of stabilizing ligands.
