In the presence of Pd(0) complexes, 2-ethoxy-2-propenyl diethyl phosphate was found to react with organotins to give the corresponding coupling products, showing to be a more efficient halo acetone equivalent compared with the corresponding acetate or carbonate. Reaction with tin enolates gave the 1,4-diketone in moderate to good yields.
在Pd(0)配合物的存在下,2-乙氧基-2-丙烯基双乙基磷酸酯与有机锡反应,生成相应的偶联产物,显示出作为氯乙酮等效物的效率高于相应的醋酸盐或碳酸盐。与锡烯醇盐的反应得到1,4-二酮,产率中等到良好。
