Derivatives of 3,3,3-trifluoropropene 1: α-sulfide 2, sulfoxide 3, sulfone 4 and bromide 6 are useful trifluoromethylated synthons. On reaction with diazo compounds, these derivatives can afford trifluoromethyl substituted pyrazolines, pyrazoles, cyclopropanes or allylsulfones in fair to excellent yields. 1,3-Dipolar cycloaddition of trifluoropropene derivatives 2–4 with N-benzyl-azomethine ylide provides
3,3,3-三氟丙烯1的衍生物:α-硫化物2,亚砜3,砜4和溴化物6是有用的三氟甲基化合成子。与重氮化合物反应后,这些衍生物可以公平地以优异的收率得到三氟甲基取代的吡唑啉,吡唑,环丙烷或烯丙基砜。三氟丙烯衍生物2 – 4与N-苄基-偶氮甲亚胺叶立德的1,3-偶极环加成可提供双取代的3-三氟甲基-吡咯烷。
