A convenient method was developed for the cyclopropanation of aryl acetates and aryl acetonitrile using vinyl diphenyl sulfonium triflate salt. The newly developed conditions are simple, mild, and compatible with a wide range of functional groups, without the need to apply an inert atmosphere, or alkali bases.
开发了一种方便的方法,该方法使用乙烯基二苯基sulf三氟甲磺酸盐对乙酸芳基酯和芳基乙腈进行环丙烷化。新开发的条件简单,温和,并且与各种官能团兼容,而无需施加惰性气氛或碱金属。
