Six α-sulfinyl phosphorus ylides 6 have been prepared and are found upon flashvacuumpyrolysis 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.

Flashvacuumpyrolysis of α-alkanesulfinyl phosphorus ylides results mainly in extrusion of Ph3P to give thioesters, presumably by 1,2-oxygen transfer in the initially formed sulfinyl carbenes; for α-arenesulfinyl ylides loss of Ph3PO to give additional products is also observed.
