The 1,1-elimination of hydrogen cyanide and formation of triplet vinylidene from the photolysis of acrylonitrile
摘要:
The single-photon photodissociation of acrylonitrile-1-d has been investigated by flash photolysis and kinetic absorption spectroscopy in the vacuum-ultraviolet region. Both electronically excited triplet vinylidene and DCN were observed. The result provides further evidence that a "vinylidene" type structure with an extended lifetime exists. Alternative primary processes were considered, particularly those involving vinyl radical or molecular acetylene formation, but they were not observed.
