| Abstract: | Reactions of ClS[OCH(CF3)2]3 and S[OCH(CF3)2]2 with Phosphorus(III) Derivatives The sulfurane ClS[OCH(CF3)2]3 reacts with Me3P to give the phosphonium salt [Me3POCH(CF3)2]+Cl?, in the case of (MeO)3P products of an Arbuzov reaction are found: (MeO)2P-(:O)OCH(CF3)2 and MeCl; the sulfurane is reduced to the sulfoxylate S[OCH(CF3)2]2. The cyclic phosphite FP[OC(CF3)2C(CF3)2O] and P[OCH(CF3)2]3 furnish derivatives of pentacoordinated phosphorus upon reaction with ClS[OCH(CF3)2]3. The sulfoxylate S[OCH(CF3)2]2 oxidises Me3P, (MeO)3P and P[OCH(CF3)2]3 to form R3P? O and R3P? S (R = Me, OMe, OCH(CF3)2). The ether (CF3)2CHOCH(CF3)2 is isolated, too. |
