Abstract
The present invention provides a method for arylating a non-halogenated diamondoid compound comprising the steps of: PA1 (a) providing a non-halogenated diamondoid compound or mixture of non-halogenated diamondoid compounds and an aromatic compound or mixture of aromatic compounds wherein at least one diamondoid compound and at least one aromatic compound are at least partially miscible; PA1 (b) mixing the compounds of step (a) to form at least a partial solution; PA1 (c) adding a reactive halide source to the mixture of step (b); PA1 (d) adding a Lewis acid to said mixture of step (c); PA1 (e) heating said mixture of step (d) to temperature above ambient and holding said heated mixture at elevated temperature; PA1 (f) recovering an arylated diamondoid compound from said solution.
