Abstract

A nonaqueous solution is used to autoxidate cobalt (II) cyclidene compounds with R3 double bonded to CH3. The fractional pressure of dioxygen influences the rate of autoxidation, ligand replacements and convergence and features of the base which is introduced. The conjugate base is formed by a method in which a preequilibrium deprotonation of the dioxygenated cobalt (II) participates. The ligand is irreversibly oxidated by the base. Quick autoxidation is caused when R2 binds to H due to an analogous deprotonation system. An increase in the insulation of the cobalt (II) compounds to the process of autoxidation is observed after the isolation of the two acidic sites.
