1-azidohexadecane

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

Procedure: Propargyl acrylate (1.10 g, 10 mmoles), hexadecyl azide (2.37 g, 10 mmoles) and tetrakis(acetonitrile)copper (I) hexafluorophosphate (74 mg, 0.2 mmoles) are dissolved in DMF (20 ml) and stirred at room temperature under nitrogen for 24 hours. The reaction mixture is poured into water wherefrom the product precipitated as a white crystalline solid (2.95 g; yield 85%; mp 72-73° C.). 1H NMR (CDCl3, δ ppm) 7.61 (s, 1H), 6.44 (d, 1H), 6.14 (dd, 1H), 5.85 (d, 1H), 5.31 (s, 2H), 4.34 (t, 2H), 1.92 (q, 2H), 1.26 (m, 28H), 0.88 (t, 3H). 13C NMR (CDCl3, δ ppm) 166.00, 142.73, 131.39, 128.04, 123.64, 57.75, 50.43, 31.89, 30.22, 29.66, 29.65, 29.64, 29.62, 29.61, 29.56, 29.47, 29.33, 29.32, 28.95, 26.46, 22.66, 14.08. MS for C12H39N3O2 calculated 377.58; found 377.20. precipitated as a white crystalline solid (2.95 g; yield 85%; mp 72-73° C.)
