RADICAL C-Se BOND CLEVAVAGE OF SELENONIUM SALTS WITH GRIGNARD REAGENTS OR MAGNESIUM METAL

Article abstract of DOI:10.1016/S0040-4039(00)95296-1

The reaction of 2-methylisoselenochromanium salt with Grignard reagents afforded the reductive ring-opened product by the single electron transfer (SET) mechanizm, not by the self-decomposition of ?-selenurane.The same reduction was observed in the reaction of the selenonium salt with magnesium metal.Some other selenonium salts were easily reduced by magnesium metal to give ring-opened products.
