Diphenylketene and ethylphenylketene react with allylic carbonates or acetates in the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium to give α-allylated esters or 1,3-dienes, respectively.For example, the reaction of diphenylketene with allyl methyl carbonate in DMF at 0 deg C gave methyl 2,2-diphenyl-4-pentenoate in 67percent yield.The reaction of diphenylketene with allyl acetate in benzene at 25 deg C gave 1,1-diphenyl-1,3-butadiene in 72percent yield.Marked solvent effects were observed.
