실험 절차
In 8 ml of N,N-dimethylformamide, 0.5 g (3.9 mmol) of tetracyanoethylene was dissolved. With stirring under ice cooling, 0.8 g (3.4 mmol) of dibutyl(3-methoxyphenyl)amine was dissolved in 2 ml of N,N-dimethylformamide and added dropwise. The mixture was stirred for 35 minutes. After the ice bath was removed, the mixture was further stirred for 2 hours. After the reaction mixture was poured into 100 ml of water, extraction with chloroform, washing with a saturated saline solution, drying over anhydrous sodium sulfate, and concentration were performed. The residue was purified by silica gel column chromatography and washed with hexane to give 0.88 g of a black crystal having a mp of 86° C. (yield: 77.2%).
