NCN-Type Pincer Complexes of Subporphyrinatoboron(III)
dataset
posted on 2017-05-26, 20:43 authored by Masaaki Kitano, Takayuki Tanaka, Atsuhiro OsukaThe first NCN-type subporphyrin pincer
complexes 3Pd and 3Pt have been synthesized
via Suzuki coupling of 2,13-diborylsubporphyrin with 2-iodopyridine,
followed by metalation with PdCl2(MeCN)2 or
K2PtCl4, respectively. 2,13-Diiminosubporphyrin 4 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 3Pd and 3Pt displayed perturbed optical
properties presumably due to the d(metal)π(subporphyrin)
orbital interactions.
