Crystal Structure and Catalytic Properties of Tetrakis(4-hydroxyphenyl) Porphyrinato Manganese (Ⅲ) Chloride (MnTHPPCl)

摘要

The crystal structure of meso-tetrakis(4-hydroxyphenyl) porphyrinato manganese chloride ( MnTHPPCl) and its supramolecular architecture based on the hydrogen bonds of one counter Cl anion with four hydrogen atoms of four —OH groups from different MnTHPPCl molecules cooperated by self-assembly of the porphyrin units were first reported. This compound crystallized in the tetragonal space group I4/m with a = 1. 39928(7) nm, 6 = 1. 39928(7) nm, c =0. 94498(10) nm, V=1.8503(2) nm~3, and Z =2. As a catalyst, MnTHPPCl also showed a high catalytic activity in the conversion from 1 -naphthylamine ( 1 -NA) to bis (4-oxo-benzo-2-cyclohexen-1 -yl) amine ( BOBCHA ) via oxidative coupling under mild conditions.
