摘要：

Rate constants and associated activation parameters for the dissociation of (solv)5Ni(isoquin)2+ (solv = solvent, isoquin = isoquinoline) in ethanol, 1-propanol, and water and of (solv)5 NiSCN+ in 1-propanol have been measured kinetically by stopped-flow spectrophotometry using H3O+ as the decomposing ion for (solv)5Ni(isoquin)2+ and copper(II) for (solv)5 NiSCN+. These data are compared with previously reported results on dissociation of (solv)5Ni(isoquin)2+ and (solv)5NiSCN+ in several donor solvents. Pathways for dissociation of both (solv)5Ni(isoquin)2+ and (solv)5NiSCN+ in the solvents studied are accommodated within an Id-type mechanism. © 1979, American Chemical Society. All rights reserved.
