Synthesis and Characterization of a New Perhalogenated Porphyrin;Journal of Chemical Society, Chemical Communication

摘要

The first synthesis of an octahalotetraalkylporphyrin (2,3,7,8,12,13,17,18 - octabromo-5,10,15,20- tetrakis(trifluoro methyl)porphinato nickel(II)) is reported; this perhalogenated porphyrin has several novel properties including a very nonplanar ruffled structure with an unusually short Ni- N distance, an extremely red-shifted optical spectrum, and hindered rotation of the trifluoromethyl groups ((Delta)G_278K =47 kJ mol^{-1< /sup>).}
