Electric Literature of 17024-12-3, The chemical industry reduces the impact on the environment during synthesis 17024-12-3, name is 9-Iodophenanthrene, I believe this compound will play a more active role in future production and life.
10261] Into an 80-mE flask were put 3.27 g (17 mmol) of3-chlorobenzamidine hydrochloride, 5.2 g (17 mmol) of 9-io- dophenanthren, 0.31 g (1.6 mmol) of copper iodide, 16 g (49 mmol) of cesium carbonate, 0.29 g (3.3 mmol) of N,N-dimethylethylenediamine, and 80 mE of dimethylformamide (DMF), and the air in the flask was replaced with nitrogen. The mixture in the flask was stirred at 1000 C. for 21 hours. Then, 0.31 g (1.6 mmol) of copper iodide and 0.29 g (3.3 mmol) of N,N-dimethylethylenediamine were added, and the mixture was stirred at 110 C. for 8.5 hours. The resulting solution was subjected to suction filtration, and the obtained solid was washed with toluene. The obtained filtrate was washed with water, and the organic layer was washed with saturated saline. Magnesium sulfate was added to the organic layer for drying, and the resulting mixture was subjected to gravity filtration to give a filtrate. The filtrate was condensed to obtain an objective substance (a brown oily substance, at a yield of 50%). The synthesis scheme of Step 1 is shown in (a-i).
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, 9-Iodophenanthrene, other downstream synthetic routes, hurry up and to see.
