Extrusion of Sulfur from pyrimidinones
Roth, Barbara,Laube, Renee,Tidwell, Mary Y.,Rauckman, Barbara S.
, p. 3651 - 3657 (2007/10/02)
Thermally mediated sulfur extrusion from 4-(phenacylthio)-2(1H)-pyrimidinones occurs rapidly in solution at 125 deg C to yield 4(3H)-(benzoylmethenyl)-2(1H)-pyrimidinones. 4-(Acetonylthio)-2(1H)-pyrimidinone, however, rearranges via an episulfide intermed
