Abstract Bicyclo [2.2. 2] octadiene-connected pyrrolo-porphyrins have been prepared by an inverse-type [3+ 1] porphyrin synthesis of a bicyclo [2.2. 2] octadiene-fused dipyrrole with a tripyrrane dicarbaldehyde. Another [3+ 1] porphyrin synthesis of pyrrole-connected porphyrins with the same or other tripyrrane dicarbaldehydes gave bicyclo [2.2. 2] octadiene- bridged diporphyrins, the central metals and/or peripheral substituents of which were ...
