摘要：
beta-Tetra(tert-butyl)porphyrin was prepared from 2-dimethylaminomethyl-4-tert-butylpyrrole and converted into porphine, the mother compound of porphyrins, in 64% yield. The dealkylation smoothly proceeded in aqueous sulfuric acid over 15min at 190degreesC under nitrogen. (C) 2004 Elsevier Ltd. All rights reserved.
