Kinetics of Oxidation of a Cuprous 2,2′,2″-Terpyridine Complex by Molecular Oxygen

Journal Article (Journal Article)

2,2′,2″-Terpyridine (terpy) has been found to form a bis cuprous complex, Cu(terpy) +, in aqueous acetonitrile solution. The reaction with molecular oxygen was found to proceed with a two-electron reduction of O . [formula omitted] The kinetics of this reaction has been studied at 25.0° over the pH range from 5.3 to 8.0, and the rate law found to be -d[Cu(terpy) ]/dt = Kexpti[Cu(terpy) ] [O ], where K = a + b[CH CN] + c[CH CN] /[terpy]xs, and a = 1.6 × 10 M sec , b = 4.8 × 10 M sec , c = 5.1 × 10 M sec , and [terpy] = [terpy] -2[Cu ], Possible mechanisms for this reaction are discussed. © 1975, American Chemical Society.
