Yield:27319-00-2 71%

Reaction Conditions:

with tetra-n-butylphosphonium chloride at 200; for 7 h;

Steps:

1.26 Example 1-26: Synthesis of 2-(3-butenyl)-4-phenoxy ether

60 g (0.35 mol) of diphenyl ether, 16.3 g (0.18 mol) of 1-chloro-2-butene, and 5.2 g (0.018 mol) of tetrabutylphosphonium chloride were reacted at 200° C. for 7 hours in the same manner as in Example 1-1 to obtain 28.7 g (0.13 mol, yield 71%) of 1-(2-(3-butenyl))-4-phenoxy ether. As a result of 300 MHz hydrogen nuclear magnetic resonance analysis of the obtained product, CH₃-C, C-CH-C, CH₂═C, C═CH-C, and a Ph peak were confirmed at 1.4 ppm (d, 3H), 3.6 ppm (m, 1H), 5.0 ppm (m, 2H), 6.3 ppm (m, 1H), and 7.1 to 7.4 ppm (m, 9H), respectively.
