Palladium-catalysed reactions of ketenes with allyl acetates or allyl carbonates: novel syntheses of 1,3-dienes and allylated esters
Abstract
The reaction of arylketenes with allyl acetates of allyl carbonates catalysed by tetrakis(triphenylphosphine)palladium selectively gives 1,3-dienes or allylated esters, respectively, in high yields.
