to carbon double bonds, addition to sulfur of 3-methylthio-1-butene precedes attack at carbon to give allylic thiosulfonium ions that form reversibly and which rearrange rapidly to -2-butenyl analogs. Likewise, rearrangement of - to -1-methylthio-2-butene occurs by way of thiosulfonium ions.
尽管亚硫基试剂通常会加成碳双键,但在3-硫基-1-丁烯的硫中添加硫之前,会攻击碳,从而生成可逆形成的烯丙基硫代ulf硫离子,并迅速重排为-2-丁烯基类似物。同样地,通过硫代离子将-重新排列成-1-甲硫基-2-丁烯。
