反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:56.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of 1.80 g (0.014 mol) of 2-cyclopentenyl acetate in 3.80 g (0.12 mol) of methanol and 0.700 g of chlorobenzene (the internal standard for chromatographic analysis) was slowly passed through a jacketed column containing 20 ml of Dowex 1-X4 (an anion exchange resin of the quaternary ammonium type) in the hydroxide form in methanol. The column was maintained at 56° C. by refluxing acetone in the jacket. The resin was then rinsed with methanol, and the combined effluent and rinsings were analyzed by gas chromatography using a 6-ft. OV-17 column programmed from 80° to 220° C. The analysis showed that 2-cyclopentenol had been formed in 96% yield and essentially 100% efficiency. No by-products were observed. The resin was then rinsed with methanol programmed from 80° to 220° C had been formed in 96% yield and essentially 100% efficiency

実験手順: Cyclopentane (1 ml), t-butyl nitrite (1 mmol), N-hydroxyphthalimide (0.2 mmol), and acetic acid (1 ml) were placed in a flask and were stirred at 80° C. in an atmosphere of argon gas (1 atm=0.101 MPa) for 20 hours. The resulting reaction mixture was analyzed to find that cyclopentanone oxime, nitrocyclopentane, cyclopentanone, and cyclopentyl acetate were formed in yields of 4%, 2%, 3%, and less than 1%, respectively. The resulting reaction mixture
