The relative reactivities of the tetrakis( N -alkylpyridinium- X - yl )-porphyrins where X = 4 (alkyl = methyl, ethyl, n -propyl) , X = 3 (methyl) , and X = 2 (methyl, ethyl, n -propyl, n -butyl, n -hexyl, n -octyl) were studied in aqueous solution. From the ionic strength dependence of the metalation rate constants, the effective charge of a particular cationic porphyrin was usually larger when copper(II) rather than zinc(II) was the reactant. The kinetics of ZnOH + incorporation and the acid catalyzed removal of zinc from the porphyrins in 1.0 M HCl were also studied. In general, the more basic 4- (para-) and 3- (meta-) isomers were the most reactive, followed by the less basic 2- (ortho-) methyl to n -butyl derivatives, with the lipophilic ortho n -hexyl and n -octyl porphyrins the least reactive.

In the oxidation of gaseous butanone the reaction rate increases with time from an initially small value to a maximum. The growth of rate in the early part of the reaction is exponential in form. Analysis for ketone shows that the consumption of butanone runs closely parallel to the increase of pressure. During the induction period peroxides accumulate and the rate of reaction is proportional to peroxide concentration. The formation of peroxides is greatly accelerated by the addition of a trace of acetaldehyde.
