An expedient, mild, reductive method for the preparation of alkylferrocenes
Abstract
Reductive deoxygenation of acylferrocenes to the corresponding alkylferrocenes proceeded in excellent yields on utilizing a combination of sodium cyanotrihydroborate and boron trifluoride–diethyl ether. This method allows the synthesis of alkylferrocenes with functionalized tethers and is adaptable to large-scale preparations.
