Pd(OAc)2 combined with PPh3 is a good catalyst for the addition reaction of CCl4 and CO to olefins in ethanol to afford ethyl 2-alkyl-4,4,4-trichlorobutanoates. The esters were obtained in satisfactory yields when the reaction was carried out at 50° in the presence of K2CO3 under CO pressure.
Pd(OAc)2与PPh 3结合是将CCl 4和CO加成乙醇中的烯烃,得到2-烷基-4,4,4-三氯丁酸乙酯的良好催化剂。当反应在50℃下在K 2 CO 3存在下在CO压力下进行时,以令人满意的收率获得酯。
