Electric Literature of 6414-69-3, The chemical industry reduces the impact on the environment during synthesis 6414-69-3, name is Ethyl 3-iodopropanoate, I believe this compound will play a more active role in future production and life.
Ethyl 3-[4-(3-Nonynyloxymethyl) phenyl]propanoate (46). A flask was charged with Zn-Cu couple (200 mg, 3 mmol) solution of ethyl 3-iodopropanoate (510 mg, 2 mmol) in dry toluene (4 mL) and dry N,N-dimethylacetamide (2mL) was added. The mixture was vigorously stirred for 1 hour at room temperature and then heated at gentle reflux for 4.5 hours. After the mixture was cooled to 60 C, a solution of tetrakis(triphenylphosphine)palladium(0)(30 mg, 0.026 mmol) in toluene (2 mL) was added over 1 minute and stirring was continued for 5 minutes at the same temperature. A solution of (45) (309 mg, 1 mmol) in dry toluene (2 mL) was added and the mixture was refluxed for 12 hours. The reaction mixture was allowed to cool to 25 C. and filtered through a Celite pad. The filter cake was washed with ether (50 mL). The filtrate was successively washed with a solution of i N ammonium chloride (10 mL), a solution of saturated sodium hydrogen carbonate (10 mL) and a solution of saturated sodium chloride (10 mL). The aqueous phases were back extracted with ether (30 mL), the combined organic extracts were dried (MgSO4), filtered, concentrated by rotary evaporation to yield a yellow oil. Purification by flash silica gel chromatography (97:03 petroleum ether/EtOAc) afforded (46) (165 mg, 51%) as a colorless oil: Rf 0.44 (95:05 petroleum ether/EtOAc); 1 H NMR (CDCl3) delta 7.19 (m, 4 H), 4.51 (s, 2 H), 4.12 (q, J=7.2 Hz, 2 H), 3.55 (t, J=7.2 Hz, 2 H), 2.94 (t, J=8.1 Hz, 2 H), 2.61 (t, J=8.1 Hz, 2 H), 2.46 (tt, J1 =6.9 Hz, J2 =2.1 Hz, 2 H), 2.13 (tt, J1 =7.2 Hz, J2 =2.4 Hz, 2 H), 1.40 (m, 6 H), 1.22 (t, J=7.2 Hz, 3 H), 0.88 (t, J=6.9 Hz, 3 H); 13 C NMR (CDCl3) delta 173.01, 140.87, 138.58, 128.68, 127.75, 81.64, 76.67, 72.99, 69.15, 60.53, 36.02, 31.01, 31.18, 28.81, 22.34, 20.28, 18.85, 14.32, 14.12.
