Hydroquinone was recently found to act as an excellent catalyst in the Gomberg-Bachmann reaction but the action was limited to the reaction of 4-diazo-3, 5-dimethyl-pyrazole with an aromatic hydrocarbon. Therefore, application of this catalyst to the same reaction of common diazonium salts was examined and it was found that hydroquinone was effective in the reaction of p-nitrobenzenediazonium tetrafluoroborate with benzene and nitrobenzene, in the presence of a base which the reaction requires theoretically. It was found that, among the bases used, 3, 5-dimethylpyrazole not only satisfied the theoretical demand of the reaction but also manifested a catalytic action.
