摘　　要：以酰氯为酰化剂 ,无水三氯化铝为催化剂 ,二氯乙烷为溶剂 ,对二茂铁进行酰化反应得到一系列酰基二茂铁 ,经Clemmenson还原法得到相应的烷基二茂铁 ,再用浓硫酸 -甲醇体系做为催化剂 ,进行二茂铁与丙酮的缩合反应 ,经层析分离得到相应的双 (烷基二茂铁基 )丙烷。通过元素分析 ,红外光谱 ,折光率的测定 ,对目标化合物进行表征 ,并用循环伏安法研究其电化学性质 。In this paper, by using acylchloride as acylating agents, anhydrous aluminium chloride as catalyst. a series of acylferrocenes were synthesized, then using Zn-Hg as reductant, alkylferrocenes were prepared through reducing acylferrocenes. And alkylferrocenes were condensed with acetone with mixure of methanol and concentrated sulfuric acid as catalyst. Through chromatography seven pure bis-(alkylferrocenyl)propane were obtained. The structure of these compounds were characterized by elemental analysis and IR spectum. The electrochemical properties of this serie compounds were investigated by cyclic voltammetry. The catalytic burning-rate of composite solid propellants with the compounds were tested.
