400 mg With acetic acid; In chloroform; for 2h;Reflux; Copper tetraphenyl porphyrin was synthesised by taking tetra phenyl porphyrin[H2(TPP)]16(500mg) in chloroform(100ml).Copper(II) acetate(200mg) in glacial aceticacid(50ml) was added to the above solution andthe mixture was refluxed for 2hrs. The contents wereconcentrated to a volume of about 50-60ml andcooled to room temperature which resulted in crudecopper-tetraphenyl porphyrin Cu(TPP) (about450mg). The crude product was purified by columnchromatography using neutral alumina andchloroform as eluent. On elution the unreactedtetraphenyl porphyrin was eluted out first, followedby pure Cu(TPP). The chloroform fraction containingCu(TPP) was concentrated to obtain pure crystalsof Cu(TPP)[2]. The formation of Cu(TPP) wasmonitored by UV-visible spectroscopy which givepeaks-around 580, 541 and 417nm respectivelyconfirming the formation of Cu(TPP) (yield=400mg).

With acetic acid; at 24.84℃;Kinetics; General procedure: The reactions of complexing between porphyrins and copper acetate were studied by means of spectrophotometry in the range of 293-318 K. The change in temperature during the experiment did not exceed±0.1 K.
In N,N-dimethyl-formamide; at 44.84℃;Kinetics; Thermodynamic data; General procedure: Porphyrins 1-6 (Aldrich, 97%), organic solvents (Merck, 99%), and inorganic salts (Acros, 99%) were used as received. The complex formation was studied by recording electronic absorption spectra of the solutions using a Cary 300 spectrophotometer (Varian). To do so,solutions of the studied porphyrin (2.5×10-5 mol/L)and the salt (2.5×10-3 mol/L) in an organic solvent were put in the cell maintained at constant temperature(±0.1C), and the absorbance at the wave length corresponding to the maximum in the spectrum of the formed metal porphyrinate was monitored. Kinetic studies of the complex formation were performed over 288-363 K range.

72% In N,N-dimethyl-formamide; for 0.00555556h;Heating; 0.05 g (0.0813 mmol) of tetraphenylporphyrin and0.144 g (0.813 mmol) of Co(OAc)2 were dissolved in70 mL of DMF, heated to boiling, boiled for 20 s, andcooled. The filtrate was poured into water, theprecipitate was filtered off, washed with water, dried,and chromatographed on alumina using dichloromethaneas the eluent [25]. Yield 0.04 g (0.0595 mmol,72%), Rf 0.77 (1 : 1 hexane-chloroform). IR spectrum,nu, cm-1: 2917, 2849 (CH, Ph), 1694, 1599 (C=C, Ph),1437 (C=N), 1350 (C-N), 1150, 1073 [delta(C-H, Ph)],1004 (Co-N), 796 [gamma(C-H, pyrrole ring)], 752, 702[gamma(C-H, Ph)], 470 (Co-N). 1H NMR spectrum(CDCl3), delta, ppm: 16.05 br.s (8H, pyrrole), 13.20 br.s(8H, Ho), 8.20 t (8H, Hm, J = 7.7 Hz), 8.01 br.s (4H,Hn). Mass spectrum, m/z (Irel, %): 671.3 (99) [M - H]+(calculated for C44H28N4Co: 672). EAS (benzene),lambdamax, nm (log epsilon): 529 (4.16), 413 (5.35). Found, %: C78.58; H 4.15; N 8.30. C44H28N4Co. Calculated, %: C78.69; H 4.20; N 8.34.
In N,N-dimethyl-formamide; at 89.84℃;Kinetics; Thermodynamic data; General procedure: Porphyrins 1-6 (Aldrich, 97%), organic solvents (Merck, 99%), and inorganic salts (Acros, 99%) were used as received. The complex formation was studied by recording electronic absorption spectra of the solutions using a Cary 300 spectrophotometer (Varian). To do so,solutions of the studied porphyrin (2.5×10-5 mol/L)and the salt (2.5×10-3 mol/L) in an organic solvent were put in the cell maintained at constant temperature(±0.1C), and the absorbance at the wave length corresponding to the maximum in the spectrum of the formed metal porphyrinate was monitored. Kinetic studies of the complex formation were performed over 288-363 K range.
