Nitric oxide monooxygenation (NOM) reaction of cobalt-nitrosyl {Co(NO)}⁸ to Co^II-nitrito {Co^II(NO₂ ^-)}: base induced hydrogen gas (H₂) evolution.

ABSTRACT: Here, we report the nitric oxide monooxygenation (NOM) reactions of a Co^III-nitrosyl complex (1, {Co-NO}⁸) in the presence of mono-oxygen reactive species, i.e., a base (OH^-, tetrabutylammonium hydroxide (TBAOH) or NaOH/15-crown-5), an oxide (O^2- or Na₂O/15-crown-5) and water (H₂O). The reaction of 1 with OH^- produces a Co^II-nitrito complex {3, (Co^II-NO₂ ^-)} and hydrogen gas (H₂), via the formation of a putative N-bound Co-nitrous acid intermediate (2, {Co-NOOH}⁺). The homolytic cleavage of the O-H bond of proposed [Co-NOOH]⁺ releases H₂ via a presumed Co^III-H intermed
