Extracurricular laboratory: Synthetic route of 16355-92-3

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

Synthetic Route of 16355-92-3, A common heterocyclic compound, 16355-92-3, name is 1,10-Diiododecane, molecular formula is C10H20I2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

3,3′-(1,9-Decanediyn-1,10-diyl)-bis-pyridine (1 mmol) and an equivalent of 1,10-diiododecane were mixed in acetonitrile (1000 mL). The mixture was refluxed for 7 days. The solvent was removed in vacuo after cooling and the resulting residue was taken up in water and partitioned between diethyl ether and water. The aqueous layer was extracted extensively with diethyl ether remove the starting materials. Most of the water was removed and the residue was transferred into methanol. Methanol was removed and the product was dried under vacuum to afford the bis-pyridinium cyclophane (40% yield). HNMR (300 MHz, D2O), 10.11 (s, 2H), 9.37 (d, J=6.3, 2H), 8.22 (dt, J=7.8, J=1.2, 2H), 8.03 (dd, J=6.3, J=7.8, 2H), 4.99 (t, J=8.1, 4H), 2.49 (t, J=6.6, 4H), 2.15-2.17 (m, 4H), 1.38-1.75 (m, 24H). CNMR, 147.73, 145.88, 142.71, 128.04, 126.46, 102.54, 74.29, 61.82, 32.44, 28.71, 27.90, 27.83, 27.40, 25.81, 20.21.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
