First examples of intramolecular Pd(0) catalysed couplings on ortho-iodinated meso-phenyl porphyrins

Abstract

Palladium catalysed intramolecular cyclisations on meso-phenyl porphyrins give access to a range of substituted porphyrins in which one or two of the phenyl ortho-carbons are bonded directly to an adjacent β-pyrrolic position.
