The N-unsaturated alkylcarbazole derivatives were synthesized by the nucleophilic unimolucular substitution reaction ($S_N1$) of carbazole with unsaturated alkyl chloride. These reactions between carbazole and unsaturated alkyl chloride were conducted in dimethyl sulfoxide (DMSO) containing alkali (NaOH or KOH) at room temperature for 4 hrs under nitrogen atmosphere. The mole ratios of carbazole, alkali and unsaturated alkyl chloride were 1:6:1, respectively. All of the compounds of starting materials and reaction products were characterized by CHN analysis, $^1H$-NMR and FR-IR spectroscopy.
