高氯酸铁在乙腈中氧化5，10，15，20-四均三甲苯基卟啉合铁（III）高氯酸盐（TMP）Fe-III（ClO 4），得到一种亚稳态物质，鉴定为（TMP）Fe-IV（ClO 4）（2），在几秒钟内衰变为已知的同分异构物质（TMP中心点+）Fe-III（ClO 4）（2）。用355 nm激光照射亚稳态物质得到高反应性瞬态，其与简单有机还原剂（烯烃和芳基烷烃）的反应比已知化合物I类似物（TMP中心点+）Fe-IV（O）（X-）快5个数量级。
Oxidation of 5,10,15,20-tetramesitylporphyrinatoiron(III) perchlorate, (TMP)Fe-III(ClO4), with ferric perchlorate in acetonitrile gave a metastable species identified as (TMP)Fe-IV(ClO4)(2) that decayed within seconds to the known isomeric species (TMP center dot+)Fe-III(ClO4)(2). Irradiation of the metastable species with 355 nm laser light gave a highly reactive transient that reacts with simple organic reductants (alkenes and arylalkanes) 5 orders of magnitude faster than known Compound I analogues, (TMP center dot+)Fe-IV(O)(X-).
