Matrix-isolated difluorovinylidenecarbene (4) has been generated by pulsed flash pyrolysis from 1-chloro-3,3-difluorocyclopropene (8a) and 3,3-difluoro-1,2-diiodocyclopropene (8b).By subsequent photolysis 4 isomerizes to difluoropropargylene (5) and difluorocyclopropenylidene (6).The identification of the three new carbenes is based on the comparison of their experimental and calculated (MP2/6-31G*) infrared spectra. - Key Words: Matrix isolation / Photochemistry / Flash pyrolysis / Carbenes
