Synthesis and Reactions of [1-(Trialkylsilyl)alkylidene[triphenylphosphoranes Alkylidenetriphenylphosphoranes 1 react with trialkyl halosilanes 2 to afford silylated alkylidenephosphoranes 5, which can be converted to acylated alkylidenephosphoranes 8 and 10 by trimethylsilyl carboxylates 6 or carboxylic anhydrides 10. Bis(acylalkylidenephosphoranes) 13-15 are available from 5 and bis(trimethylsilyl) dicarboxylates 12 or cyclic or polymeric anhydrides 16, 17.
[1-(三烷基硅基)亚烷基三苯基膦的合成与反应] 烷亚基三苯基膦1与三烷基卤硅烷2反应生成了硅烷化的烷亚基膦5,通过三甲基硅基羧酸盐6或羧酸酐10可将其转化为酰化烷亚基膦8和10。自硅烷化的烷亚基膦5与双(三甲基硅基)二羧酸盐12或环状或聚合物酐16,17反应可得到双(酰基烷亚基膦)13-15。
