Komponenten

Versuchsvorschrift

2 g of methanesulfonic acid 3-[2,6-dichloro-4-(3,3-dichloro-allyloxy)-phenoxy]-propyl ester, 1.14 g of 4-iodophenol and 1.96 g of potassium carbonate are stirred for 24 hours at 50° C. in 20 ml of dimethylformamide. The reaction mixture is poured onto water and extracted with ethyl acetate. The organic phase is washed with water and potassium carbonate solution and concentrated. Purification over silica gel yields 1,3-dichloro-5-(3,3-dichloro-allyloxy)-2-[3-(4-iodo-phenoxy)-propoxy]-benzene. 1H-NMR (CDCl3) 300 MHz: 2.28 (m, 2H), 4.13 (t, 2H), 4.22 (t, 2H), 4.58 (d, 2H), 6.10 (t, 1H), 6.71 (d, 2H), 6.81 (s, 2H), 7.55 (d, 2H)
