The reaction of phosphates 1 and 5 and thiophosphates 3 and 7 gave the olefins 2 and 6 with 0.8 – 1.6 mol eq of Lawesson's reagent in xylene at reflux. Compounds 1, 3, 8, 5 and 7 gave 2 and 6 in better yields with a small amount of AgOTf (0.1 – 0.3 mol eq) even in toluene at reflux.
磷酸盐1和5与硫代磷酸盐3和7的反应在回流下得到的烯烃2和6含0.8 – 1.6摩尔当量的Lawesson试剂在二甲苯中。化合物1,3,8,5和7,得到2和6中更好的产率与的AgOTf少量-在回流下甚至在甲苯(0.1 0.3摩尔当量)。
