Various new 1-fluoro-1-alkyl(or aryl)-2-substituted cyclobutanes were synthesized stereoselectively from 1-alkyl(or aryl)cyclopropyl carbinols by the ring expansion-fluorination using (iPr)2-KHF2-(HF)n·Py, and 2-hydroxymethyl-1-fluorocyclobutanes were synthesized via a new rearrangement of (1-alkyl(or aryl)cyclopropyl) ethylene oxides.
