摘　　要：制备了四种苯并噻唑基尾式铁（Ⅲ）卟啉，用元素分析和１ＨＮＭＲ、ＦＡＢ－ＭＳ、ＵＶ－Ｖｉｓ等谱对自由卟啉及其铁（Ⅲ）配合物进行了表征；通过铁（Ⅲ）卟啉ＥＳＲ和ＭＣＤ光谱的分析以及与咪唑加合反应稳定常数的测定，考察了铁（Ⅲ）卟啉的轴向配位状态；研究了ＰｈＩＯ存在下苯并噻唑基尾式铁（Ⅲ）卟啉对环己烷羟化反应的催化活性，结果表明，在一定条件下，尾端苯并噻唑基团与铁（Ⅲ）卟啉可发生分子间轴向配位，并对轴向加合常数以及环己烷羟化产生一定的影响。Four new 2-benzothiazolethiollinked iron( Ⅲ) porphyrins were prepared and their structures were confirmed by elementary analysis,IR, FAB-MS,1H NMR and UV-visible spectra. The characterization confirms that the tail and the porphyrin ring is connected with the alkyl chain through a thiol ether linkage,ESR and MCD spectra indicate that the iron (Ⅲ) is in the high-spin state. Coordination constants of the imidazole adducts and catalytic activity to cyclohexane all show that the tail have larger effect on the iron center than the substituents in phenyl group.
