Mechanism of the nitrous acid-catalysed aquation of aquochromium(III) complexes

T. C. Matts  and  P. Moore  

Abstract

Nitrous acid, in perchloric acid, dramatically increases the rate of aquation of Cr(H2O)5X2+(X = Cl or Br), cis- and trans-Cr(H2O)4Cl2+, and cis-Cr(NH3)4(OH2)Cl2+, but has little effect upon the rate of hydrolysis of Cr(NH3)5Br2+ and trans-Cr(NH3)4(OH2)Cl2+. The mechanism is believed to involve the formation of traces of nitrito-intermediates by O-nitrosation, with H2NO2+ or NO+ as the nitrosating agent. These preliminary results indicate that the catalysis may be stereospecifically restricted to complexes containing an aquo-ligand in a cis-position relative to the leaving group. Some new nitrito-chromium(III) compounds are reported.
