Zur Synthese von phosphorhaltigen Heterocyclen mit metallorganischen Verbindungen / Synthesis of Phosphorus Containing Heterocycles with Metal Organic Compounds

Abstract

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.
