Several natural corrinoids, cobalamin, 5-hydroxybenzimidazolyl cobamide (factor III), adenyl cobam ide (pseudovitam in B12), 2-methyladenyl cobamide (factor A) and cobyric acid, were reduc­ed with sodium borohydride. The reduction of cyanocobalam in is slow as compared with that of factor III and especially of the other corrinoids under study. At longer wavelengths (λ > 300 nm) the electronic spectra of the Co(I)-corrinoids are nearly identical. The same is to say about the CD-spectra of the Co(I)-corrinoids examined.
