Abstract

The reaction of Ta(CHCMe 3)(PR 3) 2Cl 3 and W(O)(OCMe 3) 4 yields mixed oxo-alkylidene complexes of tungsten(VI). Two have been subjected to single- crystal X-ray structural analysis. W(O)(CHCMe 3)(PEt 3) 2Cl 2 is disordered, but a full characterization of W(O)(CHCMe 3)(PMe 3) 2Cl 2 has been com- pleted. The oxo and alkylidene ligands occupy mutually cis locations with WO 1.701(15)Å, WCHCMe 3 2.006(15)Å and <OWC 101.6(8)°.
