The [2,3]-sigmatropic rearrangement of sulfur ylides derived via the desilylation of several α-trimethylsilylbenzyl sulfonium salts has been studied. The initially formed ylide was found to rapidly equilibrate with the thermodynamically more stable ylide. In the absence of trapping reagents, a Sommelet-Hauser type rearrangement occurs.
通过几种α-三甲基甲硅烷基苄基sulf盐的脱甲硅烷基化作用,研究了硫烷基化物的[2,3]-σ重排。发现最初形成的叶立德与热力学更稳定的叶立德迅速平衡。在没有捕获试剂的情况下,发生了索姆莱特-豪瑟(Sommelet-Hauser)型重排。
