Kinetics and Mechanism of Chromium(III)-Picolinato and Chromium(III)-Dipicolinato Complexes Aquation in HNO₃Solutions

26 Mechanisms of reactions in solution

“…The mechanism for the aquation of [Cr(pic)(H 2 O) 4 ] 2+ and [Cr(dpic)(H 2 O) 4 ] 2+ in HNO 3 solution involves initial protonation of the carboxylic acid oxygen-atom on a monodentate ligand. 107 There has been a review of the kinetics and mechanisms of dissociation manganese porphyrin complexes in mixed protolytic solvents. 108 A contribution to the understanding of the reactions of deoxymyoglobin (Mb-Fe(II)) provides the first demonstration of its direct reaction with HNO (nitrosyl hydride, also called nitroxyl).…”
