of diastereomerically and, by extension, even enantiomerically pure vicinal difluoroalkanes is described. The two fluorine atoms are introduced in two consecutive steps : ring opening of an oxirane by addition of hydrogen fluoride and subsequent treatment of the resulting fluorohydrine with diethylaminosulfur trifluoride.
描述了一种用于制备非对映体的方法,以及甚至扩展为对映体纯的邻位二氟烷烃的简便方法。在两个连续步骤中引入两个氟原子:通过添加氟化氢使环氧乙烷开环,然后用三氟二乙氨基硫处理所得的氟代醇。
