An effective mild procedure for the reductive deoxygenation of α-ferrocenyl aldehydes, ketones, and alcohols into the corresponding alkylferrocenes is described using a combination of zinc borohydride and zinc chloride. This is the first example of such reactivity of zinc borohydride. The present method allows the synthesis of alkylferrocenes bearing terminally functionalized pendant chains.
