实验过程
To a glass 0.5 L reaction bottle are added 20.0 g (116 mmol) of 1-oxyl-2,2,6,6-tetramethyl-4-hydroxypiperidine, 7.39 g (38.5 mmol) citric acid, 200 mg 5% Pt on C and 100 mL water. Catalytic hydrogenation is carried out at 50 psi for 30 minutes at room temperature. Catalyst is removed by filtration through a pad of Celite. The aqueous salt solution has a pH of 5.56. Removal of water yields the product as a hygroscopic glassy solid.
