4-hexamethyl-1-phenylphosphetanium iodide led to ring opening via pentacovalent intermediates as also did the action of cyanide ion on this salt. Ring expansions of 2,2,3-trimethyl- and 2,2,3,3-tetramethyl-1-phenylphosphetan on reaction with ethyl propiolate in wet ether, on reaction with dimethyl acetylenedicarboxylate, and on hydrolysis of the iodomethylphosphetanium salts, occur with migration of the
描述了磷脂的其他开环和扩环。试图由1,2,2,3,4,4-六甲基-1-苯基碘化碘生成内鎓盐导致经由五价中间体的开环,氰化物离子对该盐的作用也是如此。与2,2,3-三甲基和2,2,3,3-四甲基-1-苯基磷杂环丁酮在湿醚中与丙酸乙酯反应,与乙炔二羧酸二甲酯反应,以及碘甲基磷鎓盐水解时发生扩环。亚甲基和/或异亚丙基的迁移。2,2,3-Trimethyl-和2,2,3,3-tetramethyl-1-phenylphosphetan氧化物容易被稀碱水解,并具有开环作用,得到次膦酸。
