“…Although we do not have proof for a precise mechanism at the present stage, the reaction can be rationalized by assuming the following pathway, which is similar to that suggested by Murahashi et al: [6] The reaction of isobutyraldehyde with molecular oxygen [14] in the presence of amorphous metal/alloy and acetic acid would give perisobutyric acid, [15] which subsequently reacts with metal/alloy to afford a metal ± oxo species [16,17] along with isobutyric acid. Abstraction of a hydrogen atom from cyclohexane with the oxo-metal species followed by hydroxy ligand transfer to the resulting radical would give the alcohols.…”

“…The optimum curing ratio of anhydride and epoxide is considerably less than unity and indicates that etherification is important in the reaction mechanism. We have found also that equimolar quantities of cyclohexene oxide and acetic acid react in the following way: The epoxide-alcohol reaction, which is very slow in the absence of initiators, is apparently accelerated by carboxylic acids, as illustrated by reactions (5) and (6).…”

IntroduetionIn curing conventional epoxy resins, considerable study has been devoted to the effect of structure of polycarboxylic acid anhydrides on reactivity and resin properties. The resistance of cured resins to stress at elevated temperatures, for example, increases as the functionality or the compactness of the anhydride increases.' Pyromelletic dianhydride,2 chlorendic anhydride13 and methyl Nadic anhydride4 have been developed as curing agents leading to high softening resins. More recently, attention has also been given to the synthesis of new types of epoxides as another method of modifying the resin forming properties. The approach was stimulated by the development of economical and efficient methods of epoxidation with the use of peracetic acid.6 This paper is concerned with one of these epoxides, namely endo-dicyclopentadiene dioxide (Union Carbide Chemicals Co., Unox epoxide 207, m.p. 185OC.) : Unox 207 Anhydride Curing AgentsA variety of polycarboxylic acid anhydrides is available as curing agents for polyepoxides. The reactivities of anhydrides toward epoxides differ greatly and are related to 'the strength of the respective acids and to steric hindrance. Maleic anhydride, which is derived from a strong acid, reacts very rapidly, whereas alkenylsuccinic anhydride reacts slowly because of the bulky side chain. We have observed that maleic anhydride and Unox 207 have several unique and desirable properties in forming resins.The thermal stability of resins from Unox 207, maleic anhydride, and 2-ethyl-2-(hydroxymethyl)-l,3-propanediol (trimethylolpropane) was examined as a criterion for optimum formulations. The polyol was added to initiate the reaction. The mixtures, which are homogeneous, mobile
