Reduction of co-ordinated carbon dioxide to carbon monoxide via protonation by thiols and other Brønsted acids promoted by Ni-systems: a contribution to the understanding of the mode of action of the enzyme carbon monoxide dehydrogenase

Abstract

Carbon dioxide co-ordinated to Ni⁰ is easily reduced to bound carbon monoxide by R–SH (R = H, alkyl, benzyl, phenyl, and substituted phenyl) and other Brønsted acids, providing a reasonable model for the Ni-containing enzyme carbon monoxide dehydrogenase.
