2-propan-2-ylcycloheptan-1-one

反应条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Magnesium (3.12 g, 0.13 mole), mercuric chloride (0.1 g) and dry tetrahydrofuran (10 ml) were stirred together. Chloromethylethyl ether (12.3 g, 0.13 mole) in tetrahydrofuran (15 ml) was then slowly added at -10° C. 2-Isopropylcycloheptanone (18.5 g, 0.12 mole) in tetrahydrofuran (25 ml) was added slowly keeping the mixture at -10°. This mixture was kept for 15 hours at -10° C. Saturated ammonium chloride solution (100 mls) and dilute ammonia (50 ml) were then added. The mixture was extracted with ether and the ether extracts dried and concentrated. The residue (11 g.) was distilled bp. 115/130°/12 mm Hg, mixed with formic acid (6.5 g) and heated at 100° C. for 2 hours. The solution was extracted with ether,washed with NaHCO3 solution and dried (MgSO4). The solvent was removed and the residue (11 g), silver oxide (16.2 g, 0.07 mole) and sodium hydroxide (2.8 g. 0.07 mole ) in water (150 ml) were stirred at 30° C. for 50 hours. The mixture was filtered and extracted with ether. The aqueous layer was acidified and extracted with ether. The ether was removed and the residue was distilled to give 2-isopropylcycloheptanecarboxylic acid, bp. 120°/0.2 mm. at -10° The mixture was extracted with ether the ether extracts dried concentrated The residue (11 g.) was distilled bp 115/130°/12 mm Hg, mixed with formic acid (6.5 g) The solution was extracted with ether,washed with NaHCO3 solution dried (MgSO4) The solvent was removed The mixture was filtered extracted with ether extracted with ether The ether was removed the residue was distilled
