Reaction of tris(1,10-phenanthroline) cobalt(III) perchlorate, nitromethane and an excess of base-I reaction with pyridine

Abstract

Kinetic studies of the [Co(phen)3] (ClO4)3 2H2O nitromethane pyridine reaction were made spectrophotometrically, by recording the appearance of a new absorption band at 474 nm. The reaction is first order with respect to all three reactants. Reaction products were isolated and attempts were made to purify them. A mechanism is proposed for the reaction involving the formation of Co(phen)33+CH2NO2- (ClO4)2. The rate determining step would be the rupture of a CH bond in the solvated nitromethane molecule. © 1978.
