Optimal Regioselectivity Control in Electrocatalytic Oxidation of Terminal Olefins

Electrochemical Wacker oxidation of terminal olefins has been among the most interesting reactions from an industrial standpoint. However, the poor regioselectivity and contamination of products with palladium (Pd) catalysts have been the main drawbacks of its commercialization. Herein, rational preparation, as well as catalytic, structural, and electrochemical properties analysis of solid-supported Pd on graphene nanoplatelets (GNP) highly active catalysts for regioselective Wacker-type electrooxidation of terminal olefins is presented. The prepared catalysts improved by two orders of magnitude the electrocatalytic oxidation of 1-octene compared to the conventional homogeneously-catalyzed reactions. The control over oxidation regioselectivity via minimization of the cathodic reduction reaction was also confirmed.To be presented at: the 235th ECS Meeting, Dallas, TX. May 26-31, 2019.
