Reductive decomposition of ?-allyl palladium chloride in methanol containing sodium methylate

Abstract

1. Metallic palladium liberated in the course of reductive decomposition of π-allyl palladium chloride in methanol containing sodium methylate is a catalyst of this reaction. 2. One of the products of the reductive decomposition of π-allyl palladium chloride under the action of sodium methylate is CO2, which remains in the reaction solution in the form of the carbonate. The yield of CO2 is 1.00±0.13 mole per three groups of C3H5PdCl. 3. π-Allyl palladium chloride is capable of being reduced by sodium formate in methanol only in the presence of metallic palladium. 4. The results obtained are interpreted in the framework of a mechanism including intermediate formation of formaldehyde, sodium formate, and a complex of palladium simultaneously containing an allyl group and hydride hydrogen.
