Abstract
The reaction between W 2 (OCH 2 -t-Bu) 6 (py) 2 and each of acetone and 9-fluorenone is shown to proceed in hydrocarbon solvents at 0 o C to give oxo(μ-alkylidene)ditungsten alkoxides, W 2 (OCH 2 -t-Bu) 6 (py)-(O)(μ-CR 2 ), by reductive cleavage of the ketonic C-O bond. The X-ray structural characterization of a derivative W 2 (OCH 2 -t-Bu) 4 (O 2 CCF 3 ) 2 (py)(O)(CMe 2 ) reveals a W 2 10+ center, W-W=2.70 A, bridged by one alkoxide and a μ-propylidene ligand
