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

实验步骤: Using the general procedure of Example 2, 87.6 grams (0.2 mol) of the product of Example 5 in 800 ml of isopropanol is oxidized using 9.7 ml (0.25 mol) of 70% aqueous hydrogen peroxide solution to give 32.1 grams (44% yield) of the above-named product as a white solid melting at 85°-86° C.

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

实验步骤: Following the general procedure of Example 12, to a solution of 50 grams (0.14 mol) of didodecylamine dissolved in 200 ml of n-propanol at 40° C. is added dropwise 9.62 grams (0.14 mol) of 50% aqueous hydrogen peroxide solution. After 72 hours at 40°-45° C., the reaction mixture is filtered to give a crude product which is subsequently recrystallized from 300 ml of hexane. The above-named product is obtained in a yield of 24.8 grams (48%) as white needles melting at 90°-92° C. the reaction mixture is filtered to give a crude product which is subsequently recrystallized from 300 ml of hexane

实验步骤: A solution of dodecanal (9.2 g, 50 mmol) and hydroxylamine hydrochloride (2.0 g, 29 mmol) in 70 ml of methanol and 10 ml of ethyl acetate is shaken under hydrogen at 40-45 psi (2.8-3.15 Kg/cm2) for 2.5 hours at room temperature in the presence of a catalytic amount of 5% platinum on carbon (400 mg) and platinum oxide (15 mg). The reaction mixture is then worked up as described in Example 4 to give, after recrystallization from methanol, 4.6 g (50% yield) of the title compound as a white solid identical to that prepared in Example 4. to give

实验步骤: A solution of dodecanal (9.2 g, 50 mmol) and hydroxylamine hydrochloride (3.8 g, 54 mmol) in 75 ml of methanol and 10 ml of ethyl acetate is shaken under hydrogen at 40-45 psi (2.8-3.15 Kg/cm2) for five hours at room temperature in the presence of a catalytic amount of 5% platinum on carbon (450 mg). The reaction mixture is then filtered through CELITE filter agent. The filtrate is concentrated and the residue is treated with a saturated aqueous potassium carbonate solution till the pH is over 10. A white solid is isolated by filtration and is recrystallized from methanol to provide 4.7 g (51% yield) of the title compound as a white solid melting at 88° C. The reaction mixture is then filtered through CELITE filter agent The filtrate is concentrated the residue is treated with a saturated aqueous potassium carbonate solution till the pH A white solid is isolated by filtration is recrystallized from methanol
