Mild and simple catalytic systems consisting of molybdenum(VI) dichloride dioxide [MoO2Cl2] as a catalyst and a phosphine as reductant have been developed for the stereospecific deoxygenation of epoxides to alkenes. The reactions using 1,2‐bis(diphenylphosphino)ethane (dppe) and triphenylphosphine (PPh3) proceed with retention and inversion of stereochemistry, respectively. The mild reaction tolerates
已经开发了一种温和而简单的催化体系,该体系由二氧化钼(VI)二氧化钼(MoO 2 Cl 2)作为催化剂和膦作为还原剂组成,用于环氧化物的立体定向脱氧成烯烃。使用1,2-双(二苯基膦基)乙烷(dppe)和三苯基膦(PPh 3)的反应分别进行立体化学的保留和转化。温和的反应可容忍各种官能团的存在,并以良好的收率提供立体确定的取代的烯烃。
