I Rt OH I1 la and 113, R= C6Ha; R'= CIIa Ib and IIb, R= R'= CFI? IC and IIc, R= R'= CGH~ Carbonation of phenylallylsodium gave a mixture of acids containing about 90% CsH5CH (C02H)-CH= CH2 and 10% C6H&H= CHCH? CO? H, while reaction with acetone gave approximately equal amounts of Ib and IIb, and reaction with benzophenone yielded only IC. It was considered that these mixtures arise due to different rates of reaction at the primary ...
