실험 절차
3 ml of 1,1,2,3,3,3-hexafluoropropanesulfonic acid were added to a solution of 20 ml of tetrahydrofuran (THF) and 4.2 g of 9-ethyl-3-carbazolylamine. After cooling to 0° C., 3 ml of isoamyl nitrite were added dropwise while stirring in such a way that the temperature did not rise above 10° C. After completion of the dropwise addition, the icebath was removed and the stirring of the reaction mixture was continued for a further 4 h. 50 ml of diethyl ether were added, and the precipitate produced was filtered off by suction, washed with a little diethyl ether and dried. 7.4 g of 9-ethyl-3-carbazolediazonium 1,1,2,3,3,3-hexafluoropropanesulfonate was obtained as a yellow, finely crystalline powder.
