A procedure for synthesizing potentially anancomeric equatorial phenyl phosphites (cis-1 and eq-cis-2) is reported.Spectral characteristics and low-temperature NMR studies on the phenyl phosphites suggest that eq-cis-2 is a system with a predominant chair conformation in solution.On the contrary, cis-1 is conformationally heterogeneous.

The reaction of oxophosphoranesulfenyl chlorides RR'P(O)SCl 2 with PIII compounds has been investigated.Its mechanistic features have been elucidated by variable-temperature 31P NMR spectroscopy and stereochemical changes at PIV and PIII phosphorus centers.These studies show that in all cases phosphonium intermediates containing the sulfur bridge >P(O)-S-P(+)P(S)-O-P(+)-Cl(-).The latter decomposes by the attack of the chloride anion on the thiophosphoryl center (deoxygenation pathway). 31P NMR studies fully corroborated the observed stereochemical changes.
