Recyclable palladium catalyst in PEG/CH3CN biphasic system for electro-oxidative wacker-type reaction

Abstract

Electro-oxidative Wacker-type reaction has been developed in PEG/CH 3CN thermomorphic biphasic system. The heterogeneous solution was turned into homogeneous solution with heating to 60°C, and electro-oxidative Wackertype reactions of alkenes bearing long alkyl chains proceeded smoothly to afford methyl ketones in good yields. The recycling of PEG phase containing Pd has also been achieved.
