## Dedicated to Professor John E. Bercaw on the occasion of his 60th birthday Despite substantial research on the chemistry of ketenes, efforts to isolate or characterize the electron-deficient difluoroketene (F 2 C=C=O) have met with little success. [1] While an early claim of the preparation of

Enol and vinyl esters were successfully synthesized by the use of an iridium complex as a catalyst. The reaction of carboxylic acid with terminal alkynes in the presence of catalytic amounts of [Ir(cod)Cl] 2 and Na 2 CO 3 gave the corresponding 1-alkenyl esters. The addition of carboxylic acids to a
