1,3-Dienes were prepared from 1,4-ketoxanthates, obtained by the radical addition reaction of an S-(2-oxoalkyl) xanthate to a terminal olefin, through the DBU induced thermal elimination of sulfur dioxide from the derived 2-sulfolenes.
由S-(2-氧代烷基)黄原酸酯与末端烯烃的自由基加成反应获得的1,4-酮氧黄酸酯制备1,3-二烯,方法是通过DBU诱导从衍生的2-硫代烯烃中热消除二氧化硫。
