Reactions of Benzopentathiepin with Trialkyl Phosphites. A New Preparative Method for S-Aryl O,O'-Dialkyl Thiophosphates

Article abstract of DOI:10.1246/cl.1993.1325

Benzopentathiepin readily reacted with trialkyl phosphites to give S-<2-(alkylthio)phenyl>-O,O'-dialkyl thiophosphates and/or O,O'-dialkyl S-(2-mercaptophenyl) thiophosphates.The selectivity for formation of these thiophosphates was dramatically affected by the reaction temperature and the solvent used.
