Palladium(II)-Catalyzed Cyclocarbonylation of Enol Ester of Acetone. A Novel Synthesis of 1,3-Dioxolan-4-one

Article abstract of DOI:10.1246/cl.1993.1615

The cyclocarbonylation of isopropenyl acetate(1) to produce 2-methoxy-2,5,5-trimethyl-1,3-dioxolan-4-one(2) by use of palladium(II)-phoshine catalyst with methanol in benzene solution was studied at 100 degC under 200 atm of CO.Conversion of 1 up to 98percent and yield to 2 as high as 67percent were attained.
