Photolysis of alkylhalodiazirines: Two pathways for vinyl halide formation

Article abstract of DOI:10.1016/S0040-4039(00)97817-1

Photoacoustic calorimetry and product studios on the photochemical decomposition of methylhalodiazirines indicate two pathways for the formation of vinyl halides: 1) a [1,2] intramolecular hydrogen shift of the initially formed methylhalocarbene, 2) an excited state pathway which circumvents the ground state carbene. Results suggest that carbene/olefin or carbene/alcohol complexes are not involved in vinyl halide formation.
