Abstract

Carbonyl(bistrifluoracetato)(η⁵-cyclopentadienyl)(η²-methylbenzylacyl)tungsten (5) reacts with 1,8-diazabicyclo[5.4.0]undecen (DBU) under deprotonation to give the anionic ketenyl complex [η⁵-C₅H₅(CO)(CF₃COO)₂W(OCC(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).
