3Abstract
The first NCN-type subporphyrin pincer complexes <b>3Pd</b> and <b>3Pt</b> have been synthesized via Suzuki coupling of 2,13-diborylsubporphyrin with 2-iodopyridine, followed by metalation with PdCl<sub>2</sub>(MeCN)<sub>2</sub> or K<sub>2</sub>PtCl<sub>4</sub>, respectively. 2,13-Diiminosubporphyrin <b>4</b> was also prepared via formylation of 2,13-dilithiosubporphyrin followed by imination with aniline but was found to be unsuitable as a precursor of organometallic species. The complexes <b>3Pd</b> and <b>3Pt</b> displayed perturbed optical properties presumably due to the d(metal)π(subporphyrin) orbital interactions
