New Preparation of Ferrocene Carboxylic Acid Benzotriazol-1-yl Ester

Abstract

Ferrocene and its derivatives are very useful in the fields of chemistry, biomedicine and materials. Herein, a ferrocene derivative was synthesized in one step from benzotriazol-1-yl-oxytripyrrolidino-phosphonium hexafluorophosphate and ferrocenecarboxylic acid. Its accurate structure was determined by 1H and 13C NMR and further confirmed by X-ray diffraction analysis of the corresponding single crystal.
