Procedimiento

To a slurry of lithium aluminum deuteride (LiAlD4) (0.012 g) in anhydrous ether (1 mL) was added, with stirring, camphor (0.1 g) in ether (2 mL), followed by heating at reflux for 3 hours. After cooling to room temperature, the excess hydride was decomposed by addition of moist ether, then the organic layer was washed with brine, dried (Na2CO4) and evaporated to give a quantitative yield of deuteriated isoborneol (0.1 g). 2H NMR (hexanes): δ 3.75. See B. Belleau, J. Am. Chem. Soc., 82, p. 5751 (1960).
