Electric Literature of 627-31-6, The chemical industry reduces the impact on the environment during synthesis 627-31-6, name is 1,3-Diiodopropane(stabilized with Copper chip), I believe this compound will play a more active role in future production and life.
Diiodopropane (0.295 g, 1.00 mmol, 5.0 eq) and potassium carbonate (0.028 g, 0.20 mmol, 1.0 eq) were added to a solution of the phenol 12 (0.100 g, 0.020 mmol, 1 .0 eq) in dry acetone (5 mL). The reaction mixture was heated at 60C for 6 hours when LC/MS showed complete reaction. The reaction mixture was concentrated to dryness under reduced pressure and the residue was purified by flash chromtography (silica gel, 75/25 v/v n- hexane/EtOAc to 50/50 v/v n-hexane/EtOAc) to afford the product as a colourless oil (0.074 g, 56%). LC/MS (3.853 min (ES+)), m/z: 669.0 [M+H]+. 1H NMR (400 MHz, CDCI3) delta 7.26 (s, 1 H), 6.90 (s, 1 H), 6.68 (s, 1 H), 6.24 (d, 1 H, J = 15.3 Hz), 5.87 (d, 1 H, J = 8.9 Hz), 5.78 (m, 1 H), 5.53 (m, 1 H), 5.12 (m, 2H), 4.65 (m, 2H), 4.41 (m, 1 H), 4.1 1 (m, 1 H), 3.93 (s, 3H), 3.81 (m, 1 H), 3.40 (t, 2H, J = 6.7 Hz), 3.05 (dd, 1 H, J = 16.3, 10.1 Hz), 2.57 (m, 1 H), 2.34 (m, 2H), 1 .84 (d, 3H, J = 6.6 Hz), 0.92 (s, 9H), 0.28 (s, 3H), 0.26 (s, 3H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1,3-Diiodopropane(stabilized with Copper chip), other downstream synthetic routes, hurry up and to see.
