Treatment of Bunte salts, ZCH2SSO3Na where Z is an electron-withdrawing group, with triethylamine and calcium chloride in the presence of cyclopentadiene or 2,3-dimethylbuta-1,3-diene gives the corresponding cycloadducts of the transient thioaldehydes, ZCHS; the cyclopentadiene adducts dissociate upon heating thereby allowing transfer of the thioldehydes to dimethylbutadiene.
在环戊二烯或2,3-二甲基丁1,3-二烯存在下,用三乙胺和氯化钙处理Bunte盐ZCH 2 SSO 3 Na(其中Z是吸电子基团),得到相应的瞬态硫醛的环加合物, ZCHS;加热后,环戊二烯加合物解离,从而使硫代醛转移至二甲基丁二烯。
