  Synthesis of supine–prone bis(diene)tungsten complexes bearing catecholate and diphenylacetylene ligands

  摘要：

  Reaction of a mono(catecholato)tetrachlorotungsten(VI) complex, WCl4(O-2-1,2-C6H4) (1a), with two equivalents of (2,3-dimethyl-2-butene-1,4-diyl)magnesium gave a new class of tungsten bis(diene) complex, W(O2C6H4)(C4H4Me2)(2) (2), whose supine-prone structure was determined by NMR and X-ray analysis. The reaction of 2 with two equivalents of CF,SO,H resulted in selective removal of the prone-diene ligand to give W(O2C6H4)(C4H4Me2)(OSO2CF3)(2) (3). A similar bis(diene) complex containing diphenylacetylene complex, W(PhC drop CPh)(C4H4Me2)(2) (4), was prepared. (C) 2001 Elsevier Science B.V. All rights reserved.
