Abstract

Abstract: The triplet mercury photosensitization of trifluoroethylene proceeds via an excited molecule mechanism leading to the geminal molecular elimination of HF and the novel difluorovinylidene carbene with a zero-pressure extrapolated quantum yield of 20.8. An additional minor primary step is C= C bond cleavage giving: CF2 and: CFH. Decomposition probably occurs from the excited triplet state of C2HF3, and the ethylidene structure is not ...
