Synthesis of -pyrrole-substituted corroles by condensation of 1,9-diformyldipyrromethanes with pyrrole.

A copper triflate-mediated approach to access copper complexes of pyrrole-substituted corroles from the reaction of 1,9-diformyldipyrromethanes and an excess amount of pyrrole is presented for the first time. This procedure is a simple and efficient way for the preparation of corroles with a polymerizable substituent on -positions.
