A comparison of the relative amounts of dediazoniation, SNAr and aryne reactions of 4-chloro-3- nitrobenzenediazonium ion with methoxide ion in CH3OH and in CD3OH confirms that the dediazoniation reaction involves hydride abstraction from the alkoxide ion by the electrophilic terminal nitrogen atom of the diazonium ion. Furthermore, the relative amounts of anionic and free-radical dediazoniation are the same in CH3OH and in CD3OH. This confirms that the partitioning between the free-radical and anionic pathways for dediazoniation is on the aryl diimide and not on the free diazonium ion. Some previously reported results on the solvent effect (methanol against ethanol) for the reaction have been reinterpreted in the light of the above conclusions.

Diazonium salts were used to prepare clay–polymer nanocomposites by living free radical photopolymerization of glycidyl methacrylate. The resulting intercalated nanocomposites have an organic mass loading of ∼41 wt% and a polymer-rich surface.
