The synthesis of sultines from δ-hydroxy sulfoxides revisited
摘要:
A re-examination of a previously thought general synthesis of sultines from delta-hydroxy sulfoxides is shown to be more complicated than originally believed. The products obtained can be alpha,alpha'-dihaloxylenes or delta-halosulfones. The results are best interpreted based on carbocation stability of the key oxo-sulfoxonium salt intermediate.
