Investigation of the electrochemical reactivity and axial ligand binding reactions of tetraphenylporphyrin carbonyl complexes of ruthenium(II)

Stability constants for nitrogenous base addition to (TPP)Ru(CO) and [(TPP)Ru(CO)]+ were calculated. Spectrophotometric methods were utilized for stability constant determinations of the five-coordinate neutral complex while a combination of spectrophotometric and electrochemical techniques was utilized to calculate values for ligand addition to the cation radical. Twenty different nitrogenous bases were investigated. For (TPP)Ru(CO)(L) values of log β1 ranged from 3.62 to 5.63 and generally increased as a function of the ligand pKa. Values of log β1 for formation of [(TPP)Ru(CO)(L)]+ ranged from 2.40 to 6.63 and also increased with the ligand pKa. Comparisons were made between the measured values of log β1 and reversible potentials for the electrode reaction (TPP)Ru(CO)(L) ? [(TPP)Ru(CO)(L)]+.
