A ring-contracted sister of porphyrin, norcorrole, has been synthesized efficiently as a stable molecule by a nickel-templated strategy. The norcorrole complex is stable but exhibits a distinct antiaromatic character according to the Hückel rule. Oxidation of the norcorrole complex provides an aromatic oxacorrole complex.

担当区分：筆頭著者記述言語：英語掲載種別：研究論文（学術雑誌）

Three-dimensional superstructures of unique self-assemblies generated by exploring the conformational flexibility of various dipyrromethenes through creation of hydrogen-bonds with metal-halide anions are reported and the conformational diversity is thoroughly described in the solid and in solution by X-ray diffraction anal. and variable temperature NMR spectroscopy. The tetrahedral or octahedral structures of their precursors, various metal-dipyrromethene complexes, are also reported, based on the crystallographic data. STM images of the self-assemblies observed on graphite surfaces present interesting arrangements and appear as tubular bunches.

Self-assembly via intermolecular hydrogen-bonding between o-/m-/p-NH2 and BF2 groups on dipyrromethenes 査読有り

Ji-Young Shin, Brian O. Patrick, David Dolphin

Tetrahedron Letters 49 巻 ( 38 ) 頁： 5515 - 5518 2008年9月

担当区分：筆頭著者記述言語：英語掲載種別：研究論文（学術雑誌）

Boron difluoride dipyrromethenes bearing configurationally different amine groups on a meso-phenyl ring were prepared and crystallized. The ortho- and para-amino groups allow the phenyl group to inductively release greater electron density into the dipyrromethenes resulting in relatively strong inter- molecular hydrogen-bonding with the terminal BF2 groups, whereas the meta-analog formed weaker hydrogen-bonds. The intensities of the 1H NMR peaks in concentrated solutions all increased with F-decoupling.

Structure, formation and catalytic studies of a meso palladioporphyrin intermediate in a heck coupling 査読有り

Michael M. Jang, Ji-Young Shin, Brian O. Patrick, David Dolphin

Dalton Transaction 頁： 2598 - 2062 2008年5月

記述言語：英語掲載種別：研究論文（学術雑誌）

A meso-palladioporphyrin intermediate was isolated from a Heck reaction between an iodoporphyrin and a non-activated olefin using a Pd(PPh3)2Cl2/Et3N system; its structure was characterized by NMR, MS and X-ray crystallography. Studies on its formation indicate that the Pd(II) catalyst was reduced in situ by Et3N with the assistance of water. The catalytic activity of the intermediate was confirmed by stoichiometric and catalytic reactions using a more reactive olefin, ethyl acrylate.
