The condensation of CHCl3 with CF3CF=CF2 under phase-transfer catalysis leads mainly to CF3CFH-CF=CCl2 (1a).In the case of CF2=CFCl, a cyclopropane adduct 3b is obtained along with CHClF-CF=CCl2 (1b).The yields of adducts 1a,b or 3b are ca. 30percent.As the working conditions are simple and the starting materials are readily available, the method could provide an interesting route to some perhalogeno-cyclopropanes and short-chain hydro-halogeno alkenes.
