Abstract

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