Palladium acetate reacts with acrylonitrile to give a 1:2 mixture of (E)- and (Z)-MeCO2CHCHCN as the final product; reaction in 1,2-dichloroethane at room temperature gives a stable organopalladium compound, which has been characterized as Pd(MeCO2)2(CHCHCN) by X-ray crystrallography, and represents the first example of an acetoxypalladium intermediate isolated in the absence of stabilizing ligands
乙酸钯与丙烯腈反应,生成(E)-和(Z)-MeCO 2 CH CHCN的1:2混合物,为最终产物;在室温下于1,2-二氯乙烷中反应可得到稳定的有机钯化合物,该化合物已通过X射线结晶描记法表征为Pd(MeCO 2)2(CH CHCN ),代表了在不存在的情况下分离出的乙酰氧基钯中间体的第一个实例稳定的配体。
