A practical procedure for the selective preparation of KHCr(CO)5 is described. The use of a potassium cation in the coordination chemistry of the [HFe(CO)4]- anion is completed and extended to the coordination chemistry of the [HCr(CO)5]- anion: CO-substitution by phosphites, phosphines and phosphinites, and H-abstraction by aminophosphines. Most of the observed differences in reactivity between KHFe(CO)4 and KHCr(CO)5 can be rationalized by the stronger acidity of KHFe(CO)4.
