Procedure: trans-2-Dodecen-1-ol was prepared by reduction of the propargyl alcohol by the method described by Jones and Denmark (Org. Syn., 1985, 64, 182-8) using 6.0 g (33 mmole) of 2-dodecyn-1-ol in 25 ml of ether and 16.2 ml of Red-Al in 30 ml of ether. Kugelrohr distillation afforded 5.73 g of a clear oil. 1H NMR δ 5.66 (m, 2), 4.07 (d, 2, J=4 Hz), 2.03 (dd, 2, J=6, 13 Hz), 1.62 (br, 1), 1.4-1.2 (m, 14), 0.88 (t, 3, J=7 Hz). Kugelrohr distillation

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: cis-2-Dodecen-1-ol was prepared as described above for cis-2-decen-1-ol except that 35 g of 2-dodecyn-1-ol, 1.0 g of catalyst, and 3.0 ml of quinoline was used. A clear oil, 33.86 g, was obtained after kugelrohr distillation. 1H NMR δ 5.57 (m, 2), 4.19 (d, 2, J=5 Hz), 2.07 (dd, 2, J=6, 12 Hz), 1.5-1.2 (m, 14), 0.88 (t, 3, J=7 Hz). A clear oil, 33.86 g, was obtained after kugelrohr distillation

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-Tetradecyn-1-ol was prepared as described above for 2-dodecyn-1-ol except that 5.0 g (27 mmole) of 1-tridecyne in 200 ml of ether, 11.6 ml (29 mmole) of n-BuLi, and 874 mg (29 mmole) of paraformaldehyde was used. The reaction afforded a white solid after workup which was crystallized from petroleum ether to yield 4.78 g of white crystals, mp 44-6° C. 1H NMR δ 4.25 (m, 2), 2.20 (m, 2), 1.6-1.2 (m, 20), 0.88 (t, 3, J=7 Hz). The reaction afforded a white solid after workup which was crystallized from petroleum ether
