The transformations of trimethyl(5-methyl-2-furyl)silane and trimethyl(5-methyl-2-furyl)germane were studied upon vapor-phase oxidation by atmospheric oxygen on a V-Mo-Ag-O catalyst.Under these conditions, trimethyl(5-formyl-2-furyl)silane and trimethyl(5-formyl-2-furyl)germane are formed albeit in only 5-7percent yield.This low yield is a consequence of the thermal instability of the starting compounds and the aldehydes formed.The oxidation of 2-methyl-5-tert-butylfuran was studied under comparable conditions.The corresponding aldehyde was obtained in 30percent yield.A scheme was proposed for the catalytic oxidation of 5-substituted 2-methylfurans.
