実験手順

Diethyl-3-iodophenylphosphonate prepared according to Example 7 (2.0 g, 5.88 mmol) and 1-tridecyne (1.79 g, 9.97 mmol) were dissolved in triethyl amine (40 ml) in a two neck round bottom flask equipped with a condenser and a nitrogen dispersing tube. The flask was inerted. Triphenylphosphine (0.047 g, 0.179 mmol) and palladium acetate (0.015 g, 0.0668 mmol) were then added and the flask was heated in an oil bath to 100° to 105° C. for 40 hours. After cooling to room temperature and filtering, the triethylamine was removed on the rotary evaporator. The residue was extracted several times with acetonitrile, and the combined extracts were stripped down to a reddish brown liquid. Chromatography on silica eluting with 20% hexane in ethyl acetate gave the product as a pale yellow oil, 0.410 g, 1.045 mmol, 17.7% yield; 1H NMR (CDCl3) ∂ 0.88 (t, J=6.8 Hz, 3H), 1.18 to 1.50 (several m, 22H), 1.60 (quint, J=7.6 Hz, 2H), 2.40 (t, J=7.1 Hz, 2H), 4.11 (m, 4H), 7.38 (m, 1H), 7.55 (br d, J=7.8 Hz, 1H), 7.71 (dd, J=13.2, 7.6 Hz, 1H), 7.83 (d, J=14.1 Hz, 1H); FAB mass spectrum m/z 399 (M+Li)+.
