It is believed that this step is rate-determining, whereas the following amination step is fast. The crucial amination step from II to III could proceed either by radical addition to the N=N double bond (path A) or by direct insertion of the N=N double bond into the Co-alkyl complex II (path B). hotels shuttle for mohegan sunWebBoth 23 and the B12 coenzyme, 24, are compounds of Co (III) and both substances have all electrons paired. B,2 can be reduced to a form with Co (II) which has an unpaired electron and gives an esr signal (Section 27-9). The cobalt-carbon bond of 24 appears to be formed from 23 by removal of the cyano group and a two- electron reduction to Co (I). hotels shrewsbury town centre
