Synthesis of ferrocenyl pyrazoline derivatives and their effects on thermal decomposition of ammonium perchlorate

Abstract

Four ferrocenyl pyrazolines derivatives 3a-3d had been synthesized by the reaction of 1,3-diferrocenyl-2-propen-1-on 1 with hydrazine hydrate, then acylation with corresponding benzoyl chlorides directly. Structures of the target compounds were characterized by IR, MS, 1H NMR, 19F NMR, 13C NMR, HRMS, the crystal structures of 3a and 3b had been confirmed by X-ray single crystal diffraction. The electrochemistry behaviors of 3a-3d had been examined by cyclic voltammetry (CV), relationship between the structure of compounds and the electrochemical behavior of redox were discussed. Thermal decomposition characteristics of ammonium perchlorate (AP) were studied by differential scanning calorimetry (DSC) and thermogravimetric (TG) analysis, the results showed that 3a-3c had obviously accelerative effect on the thermal decomposition of AP.
