Abstract
2,10-Dichloro-12-trichloromethyl-6-substituted xanthato-12H-dibenzo[d,g] [1,3,2] dioxaphosphocin-6-sulfides (2a–l) with the eight-membered phosphorus and oxygen heterocyclic ring were synthesized by reacting equimolar quantities of alcohols, carbon disulfide, and 2,6,10-trichloromethyl-12H-dibenzo[d,g][1,3,2] dioxaphosphocin-6-sulfide 1 in the presence of dimethylaminopyridine (DMAP). The structures of the products were confirmed by IR, 1H, 13C, 31P-NMR, and mass spectral analyses.
