Triethylamine → Dihydrophytol

Participants

Reaction Steps

To a solution of 50.0 g (169 mmol) of 3,7,11,15-tetramethyl-2-hexadecen-1-ol in 200 mL of ethanol were added 0.3 g (3 mmol) of triethylamine and 500 mg of 5% Pd on carbon. The mixture was maintained under 50 psi (345 kPa) of hydrogen on a Parr hydrogenator for 24 h. The mixture was filtered and concentrated, and distillation afforded 41.7 g (83%) of 3,7,11,15-tetramethyl-1-hexadecanol as a clear, colorless liquid, bp 150-155° C. at 0.05 mm Hg.
