Adducts from the radical addition of xanthates to ethyl vinyl sulfide readily undergo elimination of the xanthate group upon thermolysis to give vinylic and/or allylic sulfides, depending on the structure. In the case of α-xanthyl ketones, the adducts are converted into α-keto vinyl carbinols by rearrangement of the sulfoxides derived from the vinylic and allylic sulfides.
从黄原酸酯自由基加成到乙基乙烯基硫化物上的加合物在热解时容易发生黄原酸酯基团的消除,从而得到乙烯基和/或烯丙基的硫化物,这取决于结构。在α-黄嘌呤酮的情况下,通过重排衍生自乙烯基和烯丙基硫化物的亚砜,将加合物转化为α-酮乙烯基甲醇。
