The title compounds 127/-dibenzo[l,3,2]dioxaphosphocins (3) were synthesized by the reaction of 2,2'-methylenebis(2,4-dichlorophenol) (1) with ROPXC1_2 (X = O, S) in high yield (X = 0: 62% ～85%) and characterized by IR, ~1H NMR, ~(31)P NMR, ~(13)(C NMR and MS spectra. The long-range coupling of phosphoras and carbon in ~(13)C NMR was reported in detail. The favorable mode of fragmentation of 3 in MS spectrum was also discussed.
