Importance of ion association in the induced reactions of cobalt(III)-acido complexes. 2. Nitrosation of the (NH3)5CoN32+ ion

The nitrosation of (NH3)5CoN32+ (CoN32+) in the presence of added anions Y- = Cl, NO3, ClO4 follows the rate law -d[CoN32+]/dt = (k0 + ky[Y-])[H+][HNO2][CoN 32+] with k0 = 6.6 × 102 mol-2 dm6 s-1 and ky = 1.70 × 105 (Cl), 4.48 × 103 (NO3), 2.21 × 103 (ClO4) mol-3 dm9 s-1 at 25.0°C and I = 1.0 mol dm-3 (NaSO3CF3). The rate is little affected by the ionic strength (I > 0.2 mol dm-3) and Y- = CF3SO3- does not affect the rate. The kinetic data are interpreted in terms of NO+(aq) and YNO reacting with CoN32+ with respective second-order rate constants of 3.3 × 109 and 1.9 × 108 (Cl), 3.5 × 107 (Br) mol-1 dm3 s-1. Y- species (Cl-, NO3-) are included in the products of the reaction (as CoY2+), but not via the YNO species, and the [CoY2+]/[CoOH23+] ratios at variable and constant I are interpreted in terms of competition between Cl-, NO3-, ClO4- and CF3SO3- (NO3- > ClO4- > Cl- > CF3SO3-) from within the ion-paired Y-,CoN3ONY2+ intermediates. For Y- = Cl, NO3 this species leads to 40% CoCl2+/60% CoOH23+ and 56% CoNO32+/44% CoOH23+ entry, respectively. Comment is made on the lifetime of the Y-,CoN3ONY2+ intermediate, and comparisons are made with oxidative processes involving Cl2, H2O2, and HOCl.
