Polyethylene Glycols as Efficient Catalysts for the Oxidation of Bicyclic Monoterpenes by Ceric Ammonium Nitrate in Acetonitrile under Acid-Free Conditions: Kinetic and Mechanistic Approach

Polyethylene glycols (PEG) acts as efficient catalysts for the oxidation of bicyclic monoterpenes such as borneol, isoborneol, and camphor by ceric ammonium nitrate (CAN), a laboratory desktop reagent, in acetonitrile medium under mineral acid-free conditions. The kinetics of the reactions revealed first-order dependence on in both [CAN] and [bicyclic terpene]. The rate of oxidation is accelerated with an increase in [PEG] linearly, which could be explained by considering PEG-bound oxidant (PEG-CAN) as more reactive species than (CAN) itself. The mechanism of oxidation in PEG media has been explained through the participation of PEG-bound oxidant (PEG-CAN) and bicyclic monoterpene in the slow step.

THE REACTION OF 3-METHYLTRICARBALLYLIC ACID WITH ACETIC ANHYDRIDE. ADDENDUM: ON FITTIG'S PRODUCT FROM ACYLATIVE DECARBOXYLATION OF CAMPHORONIC ACID

Two products, 2,7-dioxa-1,4,4,5-tetramethylbicyclooctane-3,6-dione (5), and 2-acetonyl-2,3,3-trimethylsuccinic anhydride (4) were identified from the base-catalysed reaction of camphoronic acid, 2(R',R" = CH3), with acetic anhydride.The former (5) is believed to be identical with the product described by Fittig and assigned an isomeric formulation.
