Oxidative Aromatic Coupling of meso-Arylamino-porphyrins
摘要:
Strategic placement of the bis-arylamino group at the meso-position of porphyrins allowed fusion of these two moieties via aromatic dehydrogenation. By placing two di(naphthalene-2-yl)amine or bis(3,5-dimethoxyphenyl)amine groups at positions 5 and 15 of the porphyrin, the oxidative aromatic coupling was directed toward closing one six-membered ring. The extension of the porphyrin chromophore leads to significant change in linear optical properties, such as a bathochromic shift of absorption and broadening of the Q-band.

A method for the Pd-catalyzed arylation of ammonia with a wide range of aryl and heteroaryl halides, including challenging five-membered heterocyclic substrates, is described. Excellent selectivity for monoarylation of ammonia to primary arylamines was achieved under mild conditions or at rt by the use of bulky biarylphosphine ligands (L6, L7, and L4) as well as their corresponding aminobiphenyl palladacycle

Enediyne compounds of the formula: (1) characterized in that the structure thereof is very simple and the production process is easy, and that the molecular length thereof is shorter than those of compounds having been proposed. Consequently, electrode assemblies comprising any of these enediyne compounds are highly promising in the application to nanomolecular wiring (nanomolecular wire) whose production has been difficult.
