摘　　要：四甲基环戊二烯与五羰基铁在二甲苯中加热回流６ｈ，即生成标题化合物１，１与碘在氯仿中反应生成Ｆｅ－Ｆｅ键断裂的铁碘化物（Ｃ５ＨＭｅ４）Ｆｅ（ＣＯ）２Ｉ２，１与氯化汞反应生成Ｆｅ－Ｆｅ键断裂的铁氯汞化物（Ｃ５ＨＭｅ４）Ｆｅ（ＣＯ）２ＨｇＣｌ３和铁氯化物（Ｃ４ＨＭｅ４）Ｆｅ（ＣＯ）２Ｃｌ４．１与氯化亚锡反应仅分离到铁氯化物４．以元素分析，ＩＲ和１ＨＮＭＲ谱表征了化合物１～４的结构．The xylene solution of tetramethylcyclopentadiene and Fe(CO)5 was refluxed for 6h.The title compound 1 was formed in moderate yield.The reaction of 1 with I2 in chloroform yielded the Fe-Fe bond cleaved iron iodide(C5HMe4)Fe(CO)2I,2.1 reacted with HgCl2,to afford the Fe-Fe bond cleaved iron mercuric chloride (C5HMe4) Fe(CO)2HgCl,3 and iron chloride(C5HMe4)Fe(CO)2Cl 4.1 reacted with SnCl2,only 4 was isolated in low yield.The structures of 1-4 were characterized by elementary analyses,IR and IHNMR spectra.
