Diphenyl-1-phenylvinylphosphine has been obtained from sodium diphenylphosphide and α-bromostyrene. The betaine formed from the phosphine and acrylonitrile cyclises to a five-membered ylid but with styrene oxide the initial betaine does not cyclise and in ethanol gives largely styrene and diphenylstyrylphosphine oxide. Methyldiphenyl-1-phenylvinylphosphonium iodide adds diphenylphosphide anion to give
由二苯基磷化钠和α-溴苯乙烯制得二苯基-1-苯基乙烯基膦。由膦和丙烯腈环化形成的甜菜碱会变成五元碘基,但与苯乙烯氧化物一起,最初的甜菜碱不会环化,在乙醇中会大量生成苯乙烯和二苯基苯乙烯基膦氧化物。甲基二苯基-1-苯基乙烯基碘化碘与二苯基磷化物阴离子加成,得到羟丙基MePh 2 [省略图示]· Ph·CH 2 ·PPh 2,与丁基锂结合,得到亚甲基缩环,其环化成四元的碘化物。在所有情况下,均通过与醛的反应来检测它们。
