Synthetic Procedures for Pd(II)-N2CP-tolyl (2)

Pd(II) Complex of 2-Ethoxy-5,10,15,20-Tetrakis(pentafluorophenyl)-21-(3’-

Tolyl)-3,7-Diaza-21,22-Dicarbaporphyrin (Pd(II)-N2CP-m-tolyl, 2-meta) and

2-Ethoxy-5,10,15,20-Tetrapentafluorophenyl-21-(4’-Tolyl)-3,7-Diaza-21,22-

Dicarbaporphyrin (Pd(II)-N2CP-p-tolyl, 2-para).

To a toluene (70 ml) solution of ethoxy substituted tetrakis(pentafluorophenyl)-

1 N2CP (1) (20.4 mg, 0.02 mmol), Pd(OAc)2 (9.4 mg, 0.04 mmol) was added and stirred for 5 h at reflux temperature. The solvent was removed by evaporation and the residues were purified by silica gel column (Wakogel C-

200) with CH2Cl2 as an eluent. Recrystallization from hexane/CH 2Cl2 gave a mixture of the tolyl complex, 2-meta (12%) and 2-para (6%) as green solids.

The two isomers, 2-meta and 2-para, were unable to separate. 2-meta:
