摘要
在N,N-二甲基乙酰胺(DMA)的水溶液中,以氯化钯(PdCl2)为催化剂,氯化铜(CuCl2)为助催化剂,催化α-十四烯选择性氧化合成2-十四酮,收率为93%.反应在氧气压力810.6 kPa下,85℃进行,反应时间6 h.催化剂重复使用4次对反应收率无显著影响.产品结构通过IR和1H-NMR进行了确定.
An efficient catalytic system for the wacker oxidation of 1-tetradecene using PdCl2-CuCl2 in combination with DMA and H2O as the solvent under eight atmospheric pressure of O2 were disclosed.This catalytic system exhibited a high catalytic activity which offorded tetradecan-2-one in 93% yild after 6 h without formation of olefinic isomers.The solution containing the catalyst could be recycled without any loss of activity and selectivity.The product was characterized by IR and 1H NMR.
