<I>cis</I> and <I>trans</I>-<I>p</I>-Cyanostyryl(pyridine) cobaloximes (I and II) and <I>cis</I> and <I>trans</I>-<I>p</I>-methoxystyryl(pyridine)cobaloximes (V and VI) were prepared by the reaction of the reduced form of cobaloxime, bis(dimethylglyoximato)(pyridine) cobalt(I), with <I>cis</I> and <I>trans</I>-<I>p</I>-cyanostyryl bromides and with <I>cis</I> and <I>trans</I>-<I>p</I>-methoxystyryl bromides, respectively. The styryl-type cobaloximes thus obtained retained the stereochemistry, <I>cis</I> or <I>trans</I>, of the starting bromides. The bromination of these styryl-type cobaloximes (I, II, V, and VI) and of the <I>cis</I> and <I>trans</I>-styryl(pyridine)cobaloximes (III and IV) in polar or non-polar solvents gave styryl-type bromides with the retention of configuration. The mercuration of these cobaloximes with mercury(II) acetate in DMF gave styryl-type mercurials, again retaining the original configuration.
