N-bromosuccinimide in the presence of 2,2′-azobis(2-methylpropionitrile) (AIBN) affords the trans-(2-bromovinyl)-heptaethylporphyrin 10 in high yield. When primary and secondary alcohols are present in the reaction mixture the corresponding (1-alkoxyethyl)-heptaethylporphyrins are formed. The trans-(2-bromovinyl)-heptaethylporphyrin undergoes some of the reactions characteristic of the vinyl groups in
