The evolution and the current trends in a new area of chemistry of organometalloporphyrins, in metalloporphyrin chemistry are reviewed. Synthesis and properties of out of plane, di—nuclear, and "Skewered" metalloporphyrins are described. The new chemistry of metalloporphyrins was initiated by the application of Cr(CO)6, metal carbonyl in general, for insertion of Cr ion (metal ions) into por— p...
