2,4-Bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson's Reagent) and its p-phenoxy derivative react with o-dihydroxybenzene derivatives, dihydroxy naphthalene and 2,2-dihydroxybiphenyl in toluene at reflux temperature to give 1,3,2-dioxaphospholane-2-sulfide derivatives, 3a–f, 8a,b and 11a,b respectively. The structure of the products has established either chemically using methanolysis
