Preparation of 2-dodecyl tetradecanoic acid: 6e
7.01 mmol (3.09 g) of 6b were allowed to decarboxylate for 5 h at atmospheric pressure and 2.5 h at reduced pressure according to general procedure E. Yield 99%.
1H-NMR (360 MHz, CDCl3): δ 0.88 (t, 6H), 1.26 (m, 40H), 1.46 (m, 2H), 1.61 (m, 2H), 2.35 (m, 1H).
13C-NMR (90 MHz, CDCl3): δ 14.3, 22.8, 27.5, 29.4-29.8, 32.1, 32.3, 45.5, 181.8.
General Procedure E (0159) The respective malonic acid was stirred at 150-160° C. at atmospheric pressure for 70 min-5 h and for further 1-5 h at reduced pressure (approx. 100 mbar) until gas formation ceased.
