Catalyzed peroxide oxidation.1 Amides and lactams are selectively oxidized to imides by f-butyl hydroperoxide or peracetic acid catalyzed by trace amounts of transition metal ions, such as manganic acetylacetonate. For example, 2-piperidone was oxidized to glutarimide (2) in 72% yield by peracetic acid2 catalyzed by the reagent. 

The effect of varied ferric and manganic acetyl acetonate concentrations with respect to viscosity is shown on Figures 7 and 8. Of note is the limiting factor Fe(AA) has on the system, where 3.0% reacts faster the 4.5% concentration. This indicates a unique catalyst concentration is needed for this system to have an optimum effect. Manganic acetylacetonate has even a greater catalyst influence in this system. At 0.75%, Mn(AAL reacts faster than elevated concentrations of either of the J acetylacetonates.

Other reaction paths are available at least in some special cases. For instance in the oxidation with manganic acetylacetonate, disulphide is believed to arise from reaction of a sulphenium ion with the thiol (equation 58) which implies that further oxidation of thiyl radicals to... 

The use of cobalt and manganese carboxylates to initiate the oxidation of a large number of olefins such as the butenes [447, 448], propylene [449], oleic [450] linoleic [451], and stearic [452, 453] acids or their derivatives and a-methylstyrene [454, 455] is well known. The kinetics of oxidation of a-methylstyrene in the presence of cobaltous and manganous acetylacetonates as well as copper phthalocy-anine have been investigated [454, 455]. The results of this study led Kamiya to postulate a mechanism involving formation of radical species by a metal dioxygen complex, equation (270), concurrent with radical generation by hydroperoxide decomposition.

An experiment was done keeping the ligand constant and varying the base metal. This was to evaluate whether the metal has an influencing factor on the overall cure rate. The catalysts used were cupric, manganic and ferric acetylacetonates. The concentration of catalyst varied from 1.50% to 8.00% by weight and were added alone and in combinations of two. The experiment consisted of viscosity measurements over time using a Brookfield Viscometer. 

Anodic oxidation of aco-bisK3,4-dimethoxyphenyl) alkanes (47) gave the same products, but in better yields, as were obtained from oxidation with manganic tris-(acetylacetonate) for n < 6, monomeric products were obtained, whereas for n > 6, dimeric products resulted. 

Oxidation of thiols to disulphides can be brought about by using Ij, KaFe(CN)g, FeClg, l,3-dihydro-l-hydroxy-3-oxo-l,2-benziodoxole, or manganic tris(acetylacetonate). ...
