研究了ＴＰＰＦｅＣｌ和６种具有不同空间结构的氯合、中位四（邻烷基苯基）卟吩合铁（Ⅲ）［Ｔ（ｏ－Ｒ）ＰＰＦｅＣｌ，Ｒ＝Ｍｅ、ＥＴ、ｎ－Ｐｒ、ｎ－Ｂｕ、ｉ－Ｐｒ和ｔ－Ｂｕ］催化亚碘酰苯使环己烷羟基化反应。发现邻位烷基取代的铁卟啉的催化速率和催化产率都比ＴＰＰＦｅＣｌ的大，这７种铁卟啉的催化速率和催化产率（％）大小顺序分别为［Ｔ（ｏ－Ｒ）ＰＰＦｅＣｌ，Ｒ＝］ｉ－ｐｒ＞Ｅｔ＞ｔ－Ｂｕ＞ｎ－ｐｒ＞Ｍｅ＞ｎ－Ｂｕ＞ＴＰＰＦｅＣｌ和ｉ－Ｐｒ（５８）＞Ｅｔ（５７）＞ｎ－Ｐｒ（５２）＞Ｍｅ（５０）＞ｎ－Ｂｕ（４８）＞ｔ－Ｂｕ（４６）＞ＴＰＰＦｅＣｌ（３５），根据研究结果，认为邻位烷基的空间作用可能加速了铁卟啉与亚碘酰苯加成中间体中碘—氧键断裂，助进了高价铁氧酰活性中间体形成，提高了催化速率和催化产率。
The effects of TPPFeCl and six kinds of iron (Ⅲ) [T (o-R) PPFeCl, R = Me, ET, n-Pr, n-Bu, i-Pr and t-Bu] to catalyze the iodination of cyclohexane to hydroxylation. The results showed that the catalytic rate and catalytic yield of ortho-alkyl-substituted iron porphyrins were both higher than that of TPPFeCl. The order of catalytic rate and catalytic yield (%) of the seven iron porphyrins were [T (o-R) PPFeCl, R =] i-pr> Et> t-Bu> n-pr> Me> n-Bu> TPPFeCl and i-Pr 58> Et 57> n-Pr 52> Me 50 According to the results of the study, it is considered that the spatial interaction of ortho-alkyl groups may accelerate the oxidation of iodine in the iron-porphyrin and iodosobenzene addition intermediates. Oxygen bond rupture, contributed to the formation of high-priced activity of ferroxyl intermediates to improve the catalytic rate and catalytic yield.
