摘要：

Carbonyl(bistrifluoracetato)(eta5-cyclopentadienyl)(eta2-methylbenzylacyl)tungsten (5) reacts with 1,8-diazabicyclo[5.4.0]undecen (DBU) under deprotonation to give the anionic ketenyl complex [eta5-C5H5(CO)(CF3COO)2W(O=C=C(H)C6H4CH3][DBUH] (3). Subsequent treatment of 3 with trifluoroacetic acid, trimethyloxonium tetrafluoroborate or methanol affords the original acyl complex (5), its methyl substituted derivative (6) or an ester (7).
