Interaction of dialkyl disulfides with C-N,N-dimethylaminomethylene-P-phenylphosphine 1a results in the complete cleavage of the P=C double bond and formation of S,S-dialkylphenyldithiophosphonites.Ethyl sulfenylchloride undergoes dehydrochlorination by 1a, while phenyl sulfenylchloride cleaves the P=C bond in C-N,N-dialkylaminosubstituted phosphaalkenes with the predominant formation of either PhP(SPh)2 6 or PhP(SPh)Cl 7 depending on the phosphaalkene used and reaction conditions. Key words: C-(N,N-dialkylamino) substituted phosphaalkenes; disulfides; sulfenylchlorides.

The methylthio-chlorophosphanes RP(Cl)SMe are prepared in good yields (62-65percent) by condensation reactions of the corresponding dichlorophosphanes RPCl2 with methanethiol in the presence of trimethylamine (molar ratio 1:1:1). 1 and 3 have been used to produce 3-phospholene sulfides in a one-pot process by reaction with 1,3-dienes at 70 to 100 deg C.Reaction proceeds via -cycloadducts, which in suitable cases can be isolated and used for the preparation of the corresponding 3-phospholene oxides.New compounds were characterized by elemental analysis and spectroscopic investigations (NMR, MS). - Keywords: Methylthio-chlorophosphanes, 3-Phospholene Sulfides and Oxides, Mass Spectra, NMR Spectra
