Reaction Conditions:

with sodium acetate;potassium carbonate in N,N-dimethyl-formamide;chlorobenzene at 150;

Steps:

4.4 General procedure for M(TPP)
General procedure: In a 250mL distillation flask, 5,10,15,20-tetraphenylporphyrin (H₂TPP) (0.50g, 0.81mmol) and NaOAc (0.30g, 3.6mmol) was stirred in 75mL of chlorobenzene and 50mL of DMF. After the addition of two equivalents of metal acetate, a Soxhlet extractor with a cellulose filter thimble filled with ～3g of K₂CO₃ was attached to the distillation flask. The assembly was completed with a condenser on the top of the extractor; and then the mixture was heated to reflux at 150°C overnight. The reaction extent was monitored by TLC or UV-Vis until all the H₂TPP was consumed. After the reaction was compete, the solvent was removed under vacuum. The remaining solid was dissolved in 150mL of chloroform, and washed with water (50mL×3). The organic layer was further washed with a saturated sodium bicarbonate solution (50mL×3), and then dried over K₂SO₄. After removal of the solvent in vacuo, the solid was recrystallized from chloroform/heptane.
