Vilsmeier-Haack formylation of ReO and Au -triarylcorroles over 16-18 hours affords moderate to good yields (47-65%) of the ReO-3-formyl and Au-3,17-diformyl derivatives in a highly regioselective manner. Formylation was found to effect substantial upshifts for redox potentials (especially the reduction potentials) as well as significant to dramatic redshifts for both the Soret and Q bands.
在16 - 18小时内，对ReO和金 - 三芳基卟啉进行Vilsmeier - Haack甲酰化反应，以高度区域选择性的方式得到了产率中等至良好（47 - 65%）的ReO - 3 - 甲酰基衍生物和金 - 3,17 - 二甲酰基衍生物。研究发现，甲酰化作用会使氧化还原电位（尤其是还原电位）大幅升高，同时使Soret带和Q带发生显著至极大的红移。
