摘要
[GRAPHICS] Oxidative cross-coupling of acrylates with vinyl carboxylates was first successfully achieved by the use of a Pd(OAc)(2)/HPMoV/O-2 system in fair to good yields. For instance, the reaction of n-butyl acrylate with vinyl acetate in the presence of catalytic amounts of Pd(OAc)(2) and H(4)PMo(11)Vo(40)(.)nH(2)O under O-2 in acetic acid at 70 degreesC for 12 In afforded the corresponding cross-coupling product, n-butyl 5-(acetoxy)-2,4-pentadienoate, in 70% yield.
