Flash vacuum pyrolysis of sulphonyl stabilised phosphorus ylides: generation and reactivity of sulphonyl carbenes
Abstract
Thermal decomposition of arylmethylsulphonylalkylidenetriphenylphosphoranes results in loss of Ph3P and SO2 to give alkenes and in some cases products derived from benzylic radicals, the products are explained by a mechanism involving sulphonyl carbenes.
