Polyhalogeno-allenes and -acetylenes. Part 14. The reactions of Perfluoro-1,2-dienes with Dichloro- and Difluoro-carbene, and a New Route to 1,1-Dichloroperfluoro-1,2-dienes

Perfluoro-1,2-dienes RF(CF3)C=C=CF2 (RF = CF3 or n-C3F7) react in the gas phase with difluoro- and dichlorocarbene to give methylenecyclopropanes RF(CF3)CCF2C=CX2 (RF = CF3, n-C3F7; X = F, Cl) in good yield by an addition-rearrangement sequence.Pyrolysis of 1-dichloromethylene-3,3-difluoro-2,2-bis(trifluoromethyl)cyclopropane results in extrusion of difluorocarbene and the formation of 1,1-dichloro-4,4,4-trifluoro-3-trifluoromethylbuta-1,2-diene in high yield.This new allene reacts readily with methanol and undergoes efficient Diels-Alder additions to the perfluoroalkyl-substituted double bond.
