✦ Synopsis

Novel 6-alkylcarbamato/thiocarbamato-2, I O-dichlorodibenzo [d,~[l,3,6,2]dioxathiaphosphocin 6-oxides were synthesized by cyclization of 5,5'-dichloro-2,2'dihydroxydiphenyl sulfide with the corresponding dichlorophosphinyl carbamates/thiocarbamates that were obtained by the addition of alcohols/thiols to dichloroisocyanatophosphine oxide and were characterized by IR, 'H, 13C, 31P NMR, and mass spectral studies. A I3C NMR analysis revealed 2Jpoc and 3Jp0cc couplings.
