Flash vacuum pyrolysis of stabilised phosphorus ylides. Part 13.1 Extrusion of Ph3P from sulfinyl ylides and reactivity of the resulting sulfinyl carbenes

Six α-sulfinyl phosphorus ylides 6 have been prepared and are found upon flash vacuum pyrolysis at 500°C to undergo mainly extrusion of Ph3P to give thioesters, presumably by 1,2-oxygen transfer in the initially formed sulfinyl carbenes; for α-arylsulfinyl ylides loss of Ph3PO to give additional products is also observed.
