Darstellung und charakterisierung von trifluormethylthio-cyclopropanen

The reactions of dihalogenocarbenes (CX₂, X = F, Cl, Br) with CF₃SCHCH₂ or (CF₃S)₂CCH₂ yield the corresponding substituted cyclopropanes. 1,1-Dibromo-2-trifluoromethylthio- or 1,1-dibromo- 2,2-bis(trifluoromethylthio)cyclopropanes react with (nC₄H₉)₃SnH to form trifluoromethylthio - or 1,1-bis(trifluoromethylthio)cyclopropane in good yields. Physical and spectroscopic data of the new substances are provided.
