Heteromolecular insertion of EtNCX (X = O, S) and RCN (R = CH3, C6H5) into tungsten hexachloride

Heteromolecular insertion of EtNCX (X = O, S) and RCN (R = CH3, C6H5) into tungsten hexachloride The interactions of tungsten hexachloride with EtNCX (X = O, S) and RCN (R = CH3, C6H5) were studied. In the case of E = CH3, heterocumulenes are inserted at the W-Cl bond, while in the case of R = C6H5, they were inserted at a multiple tungsten-nitrogen bond of an intermediate imido complex [WCl4(NCPh)(CNCl2Ph)]. The IR, MALDI TOFF mass spectroscopy, and elemental analysis data confirmed that these interactions yielded the products of heteromolecular insertion, namely, [WCl4{(EtNCO)2(MeCN)Cl}], [WCl4(EtNCS)2(MeCN)Cl], [WCl4N(CCl2Ph)C(=NEt)O}], and WCl4N(CCl2Ph)C(=NEt)S}], whose compositions and structures were determined by the nature of the organic nitrile radical. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Coordination Chemistry Springer Journals
