Abstract The derivatives of 4-aryl-1,3,2-dioxaphosphorinane-2-sulfide, namely, 4-aryl-5,5-dimethyl-1,3,2-dioxaphosphorinane-2-sulfides (6) were synthesized in moderate yields by the cyclization reaction of 1-aryl-2,2-dimethyl-1,3-propanediols(5) with Lawesson's reagent using acetonitrile as a solvent. 8-Membered cyclic trithiopyrophosphon...
