α-Trimethylsilyl-substituted sulphoxides and sulphides undergo rearrangement with loss of the silyl group when treated respectively with trifluoroacetic anhydride and with N-halogenosuccinimide in the presence of trifluoroacetic acid, giving α-acyloxy sulphides and α-halogeno sulphides.
当在三氟乙酸存在下分别用三氟乙酸酐和N-卤代琥珀酰亚胺处理时,α-三甲基甲硅烷基取代的亚砜和硫化物会发生甲硅烷基损失的重排,得到α-酰氧基硫化物和α-卤代硫化物。
