| | 2-(1-Cyclohexenyl)ethylamine Usage And Synthesis |
| Chemical Properties | CLEAR COLOURLESS TO LIGHT YELLOW LIQUID | | Uses | 2-(1-Cyclohexenyl)ethylamine has been employed:
- as substrate for allylic hydroxylation reaction
- in preparation of thin films and single crystals of 2-(1-cyclohexenyl)ethyl ammonium lead iodide, used to fabricate optoelectronic-compatible heterostructures
| | Synthesis | 125 ml of ethylamine was placed in a 250 ml three-necked flask, which had previously been flushed with argon, at -70 ° C. 6.27 g (50 mmol) of 2-phenylethylamine was added. The resulting clear, colorless solution was metered in with 1.14 g (164.2 mmol) of Li powder; the solution turned dark blue 5 minutes after the onset of turbidity. After stirring for 2 hours at -70 ° C, the mixture was warmed to -30 ° C. Then another 0.24 g (34.6 mmol) of Li powder was added. After stirring again at -30 ° C. for 2 hours, the cooling bath was removed. The reaction mixture was allowed to warm to room temperature overnight. The reaction mixture was then given 25 ml of abs. After that, a gray suspension formed. After stirring for 20 minutes at room temperature, 25 ml of water was slowly added (exothermic temperature 40 ° C.). The excess ethylamine was then distilled off at 40 °C. The distillation residue was evaporated to dryness. Then, 100 ml of water was added and extracted 3 times with 80 ml chloroform. The combined organic phases were dried over Na?SO?, filtered, and evaporated. The
2-(1-Cyclohexenyl)ethylamine was obtained in a GC yield of 69.8%. |
