Weitere Beobachtungen zur Reaktion von Corrinoiden mit Kohlenmonoxid und Chlorkohlensäureestern / Further Experiments about the Reaction of Some Corrinoids with Carbon Monoxide and with Esters of Chloroformic Acid
The results of new experiments indicate that, in alcoholic solution, CO reacts with CoIII- and not with CoII-corrinoids; corrinoids with the lactam ring at ring B (dehydro cobalamin and dehydro cobinamide) react similar like the native substances; the products of the reaction are cobaltalkoxycarbonyl-corrinoids, which can also be synthesized by means of esters of chloroformic acid. In water, diaquo-dehydro-cobinamide can be reduced by CO to the CoII-form; this indicates that in water CoIII-corrinoids, but not CoII-corrinoids, principally react with CO, since dehydro-corrinoids are not self-reducing.
