Abstract
Reaction of 1-substituted 1-siloxycyclopropanes and aryl trifluoromethanesulfonates in the presence of catalytic amounts of tetrakis(triphenylphosphine)palladium(0) in hexamethylphosphoric triamide under carbon monoxide (10-20 atm) produces 1,4-dicarbonyl compounds (1,4-keto esters and 1,4-diketones) in moderate to good yield.Keywords
