TMSCFX2 (X = Cl, Br; TMS = trimethylsilyl) have been developed as halofluorocarbene (CFX, X = Cl, Br) precursors for [2+1] cyclopropanation with alkenes. Structurally diverse halofluorocyclopropanes were obtained in good to excellent yields. It was found

Halocyclopropyl substituted phenoxyalkanoic acids and esters thereof, having hypocholesteremic activity are prepared via several alternative synthetic approaches, involving as the key reactions interaction of a substituted phenylalkene with a carbene source to introduce the halocyclopropyl moiety, and reaction of a substituted phenol with chloroform and a lower-alkanone in the presence of base, or with a lower-alkyl α-bromo-alkanoate, to form the phenoxyalkanoic acid moiety.
