- Preparation and -Cycloaddition of Methylthio-chlorophosphanes RP(Cl)SMe (R = Me, Et, Ph)
-
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
