  Intramolecular benzoate exchange in benzoato meso-tetra (4-methoxyphenylporphyrinato) thallium(III), Tl(tmpp) (C6H5CO2)

  摘要：

  The new compound benzoato meso-tetra(4-methoxyphenylporphyrinato)thallium(III), Tl(tmpp)(C6H5CO2), has been synthesized and its molecular structure determined by X-ray analysis. The coordination sphere of the Tl3+ ion is an approximate square-based pyramid in which the apical site is occupied by an asymmetric-bidentate C6H5CO2- group. The average Tl-N bond distance is 2.24(1) Angstrom and the Tl atom is displaced 0.811 Angstrom from the porphyrin plane. The Tl(1)-O(5) and Tl(1)-O(6) distances are 2.57(2) and 2.27(2) Angstrom, respectively. Variable temperature C-13 NMR measurements show that the benzoato group of Tl(tmpp)(C6H5CO2) in CD2Cl2 solvent undergoes intramolecular exchange. In the slow exchange region, the carbonyl and C-1 '' carbons of the benzoato group are separately located at 167.8 ppm [with (2)J(Tl-C-13) coupling constant 212 Hz] and 128.3 ppm [with (3)J(Tl-C-13) coupling constant 282 Hz] for Tl(tmpp)(C6H5CO2) in CD2Cl2 at -90 degrees C. In the fast exchange region, the C*OO and C-1 '' carbons of the C6H5CO2- ligand in CD2Cl2 at 21 degrees C are singlets at 168.4 and 130.3 ppm, respectively. The comparison of the ring current effect (Delta delta) for the benzoate ligand of Tl(tmpp)(C6H5CO2) and benzoato meso-tetra(4-methoxyphenylporphyrinto)tin(IV), Sn(tmpp)(C6H5CO2)(2), is also reported.
