The preparation of (CH3)3SnSPSFC2H5, Pb(SPSFCH3)2, Pb(SPSFC2H5)2 and CH3HgSPSFCH3 is described. On the basis of NMR the structure was formulated as ... All the complexes are colourless and monomeric in solution. The magnetic and reflectance spectra of Cr(S2PFCH3)3, Mn(S2PFC2H5)2, Co(S2PFCH3)2, Ni(S2PFCH3)2 and Ni(S2PFC2H5)2 are reported and interpreted.
1 reacts with SCl2 to yield 2. The methylsilane derivatives [OC–NCH3–CO–NCH3-SO2–N]nSi(CH3)4-n for n = 2, 3 and 4 are readily prepared from 1 and (CH3)2SiCl2, CH3SiCl3 and SiCl4. The IR and mass spectra are reported.
CH3P(S)(NCO)2 reacts with [(CH3)3Si]2N-CH3, [(CH3)3SiNCH3]2CO and [(CH3)3Sn]3N to give the cyclic compounds 2a-2c. The structures are discussed on the basis of NMR and IR data. In 2 a and 2 b the (CH3)3Si-groups are easily and quantitatively replaced by protons with water under formation of (CH3)3Si-O-Si(CH3)3. By the reaction of CH3P(S)(NCO)2 with [(CH3)3Si]2S 4 is obtained, a cyclic compound with a sulfur atom of coordination number 2.
FP(S)(NCS)2 was used to investigate the scope of these reactions. With [(CH3)3Si]2NCH3 and FP(S)(NCS)2 5 is obtained, which reacts with S2Cl2 to yield 6, a bridged disulfur compound. This method may be useful for the systematic investigation of new cyclic compounds.
