Small Rings, 83 [1] . — C 3 F 2 Isomers: Generation by Pulsed Flash Pyrolysis and Matrix‐Spectroscopic Identification Matrix‐isolated difluorovinylidenecarbene ( 4 ) has been generated by pulsed flash pyrolysis from 1‐chloro‐3,3‐difluoro‐cyclopropene ( 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.
