Protonation-triggered generation of acylcobalt species from alkyne-[Co2(CO)6] complexes and their reaction with alkenes.
An efficient protocol for the generation of acylcobalt species from alkyne-[Co(2)(CO)(6)] complexes is realized by treatment of the complexes with AcOH and pyridine. The generated acylcobalt species smoothly underwent addition reactions with various alkenes to give alkyl alkenyl ketones in good yield.
