Provided is a process for the preparation of certain 1,4-bicyclo[2.2.2]octane derivatives. The new synthetic procedure involves treating 1,4-dimethylene cyclohexane with an oxidizing agent in the presence of a transition metal catalyst to afford an oxo-substituted bicyclo[2.2.2]octane species. This intermediate structure can then be further derivatized. The processes of this disclosure thus affords a novel and simplified means for the commercial production of a wide variety of bicyclo[2.2.2]octane derivatives.

Several routes to the synthesis of 1,4-disubstituted bicyclo[2.2.2]octanes have been explored and the syntheses of several such derivatives are reported. The 1,4-disubstituted bicyclo[2.2.2]-octane nucleus could not be prepared through an elimination reaction on a corresponding 2,5-disubstituted derivative or by the Diels–Alder reaction of various dienophiles with dimethyl 1,3-cyclohexadiene-1,4-dicarboxylate

Aliphatic-cored di-1,2,4-triazole ligands form both a metal–organic nanotube (MONT) and a coordination polymer upon reaction with silver nitrate. Control of the conformation of the cyclohexane ring between the triazoles determines the reaction outcome where a boat (formed from bicyclo[2.2.2]octane) yields a MONT while a chair (formed from cyclohexane) yields a coordination polymer.
