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,H-　1　NMR,　F-19　NMR,　C-13　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.　(C)&　nbsp;2021　Elsevier　B.V.　All　rights　reserved.
