Pm. Reddy et al., SYNTHESIS AND CHARACTERIZATION OF 6-ALKYLCARBAMATO-2,10-DICHLORODIBENZO[D,G] [1,3,6,2]DIOXATHIAPHOSPHOCIN 6-OXIDES, Heteroatom chemistry, 7(3), 1996, pp. 165-169
Novel 0-dichlorodibenzo[d,g][1,3,6,2]dioxathiaphosphocin 6-oxides were
synthesized by cyclization of 5,5'-dichloro-2,2'-dihydroxydiphenyl su
lfide with the corresponding dichlorophosphinyl carbamates/thiocarbama
tes that were obtained by the addition of alcohols/thiols to dichloroi
socyanatophosphine oxide and were characterized by IR, H-1, C-13, P-31
NMR, and mass spectral studies. A C-13 NMR analysis revealed (2)J(POC
) and (3)J(POCC) couplings. (C) 1996 John Wiley & Sons, Inc.
