1,3-Dipolar cycloaddition of diazomethane to (1,1-difluoroallyl)phosphonates was examined to give pyrazolines functionalized by a diethoxyphosphoryldifluoromethylene unit. The pyrazolines were transformed to the cyclopropane derivatives possessing a diethoxyphosphoryldifluoromethylene functionality by photolysis.
研究了重氮甲烷与 (1,1-二氟烯丙基) 膦酸酯的 1,3-偶极环加成反应,得到了由二乙氧基磷酰基二氟亚甲基单元官能化的吡唑啉。吡唑啉通过光解转化为具有二乙氧基磷酰二氟亚甲基官能团的环丙烷衍生物。
