P-Halogenobis(methylene)phosphoranes 2 are prepared in quantitative yield by the reaction of P-tris(trimethylsilyl)methyl-bis(trimethylsilyl)methylenephosphine (1) with elementary iodine (Method A) and catalytic isomerization of P-chlorobis(trimethylsilyl)-methyl-bis(trimethylsilyl)methylenephosphine (3) (Method B).
通过 P-三(三甲基硅烷基)甲基-双(三甲基硅烷基)亚甲基膦 (1) 与基本碘的反应(方法 A)和 P-氯双(三甲基硅烷基)甲基-双(三甲基硅烷基)亚甲基膦 (3) 的催化异构化反应(方法 B),可以定量制备对卤双(亚甲基)膦 2。
