The synthesis of the reported cyclic phosphine sulfides (4, 5, 6) is carried out in good yields in a one-pot reaction with simultaneous addition of the three reagents (1, BrMgCH2(CH2)(n)CH2MgBr, RMgBr) and final treatment with sulfur. The new phosphorus donating reagent benzothiadiphosphole 1 is an inexpensive, facile to prepare, and air-insensitive solid.

Abstract
The synthesis of the reported cyclic phosphine sulfides (4, 5, 6) is carried out in good yields in a one-pot reaction with simultaneous addition of the three reagents (1, BrMgCH2(CH2)(n)CH2MgBr, RMgBr) and final treatment with sulfur. The new phosphorus donating reagent benzothiadiphosphole 1 is an inexpensive, facile to prepare, and air-insensitive solid.File in questo prodotto:
