Silverman, R.B. and David Dolphin
J. Am. Chem. Soc.
Experimental details for the previously reported reactions (B. B. Silverman and D. Dolphin, 1973) of cobaloximes and cobalamins with Et vinyl ether or (vinyloxy) ethanol to give (2,2-diethoxyethyl) or (1,3-dioxolan-2-ylmethyl) derivatives, are presented. A rationale for the existence of Co(III) π-complexes is discussed.
