Rate and equilibrium constants have been determined over a range temperature for the reactions of zinc meso-tetraphenylporphyrin with pyridine (in chlorobenzene, 1-chlorobutane and toluene), with 2-methylpyridine (in 1-chlorobutane), and with imidazole (in 1-chlorobutane).Rates were measured by means of an improved microwave temperature-jump apparatus incorporating signal-averaging, and at low temperatures by the stopped-flow method, with spectrophotometric detection.The forward rate constants are lower by about an order of magnitude than the values calculated for diffusion control from the simple Smoluchowsky model.A two-step mechanis appears likely.Solvent and steric effects on the rate are discussed.
