Origin of the deactivation in styrene aziridination by aryl azides, catalyzed by ruthenium porphyrin complexes. Structural characterization of a Δ2-1,2,3-triazoline RuII(TPP)CO complex

The reaction of Ru(TPP)CO (TPP = dianion of tetraphenylporphyrin) with 1-(p-nitrophenyl)-5-methyl-5-phenyl-1,2,3-triazoline yielded a Δ2-1,2,3-triazoline ruthenium(II) porphyrin complex, which is responsible for the catalyst deactivation in the aziridination reaction of α-methylstyrene by p-nitrophenyl azide.

Solvent-binding and solvation effects on the electrode reactions of tetraphenylporphyrin carbonyl complexes of ruthenium(II)

The electron-transfer reactions of (5,10,15,20-tetraphenylporphyrin)ruthenium(II) carbonyl, (TPP)Ru(CO), was investigated in 12 nonaqueous solvents. In 10 of these solvents the complex existed in solution as (TPP)Ru(CO)(S), where S is a solvent molecule. This complex could be reversibly oxidized to yield [(TPP)Ru(CO)(S)]+ or reduced to yield [(TPP)Ru(CO)(S)]-. Potentials for the former reactions were related to the Kamlet and Taft β parameter while those for the latter reactions were linearly related to the solvent acceptor number. Stability constants were calculated for addition of each solvent molecule as a sixth axial ligand to (TPP)Ru(CO) in CH2Cl2-0.1 M TBAP. Stability constants for formation of (TPP)Ru(CO)(S) ranged from log β1 = 1.46 for addition of nitromethane to log β1 = 4.63 for pyridine addition. Finally, correlations were made between the stability constants and the spectral properties of each complex.
