Application of 455-13-0, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 455-13-0, name is 4-Iodobenzotrifluoride belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To a solution of aryl iodide (10 mmol, 1.0 equiv.) in THF (10 mL, 1.0 M) was added 2-propyn-1-ol (1.24 mL, 1.2 equiv.), diisopropylamine (1.68 mL, 1.2 equiv.), PdCl2(PPh3)2 (0.3 mmol, 3 mol%) andCuI (0.5 mmol, 5 mol%). The resulting solution changed colour from yellow to orange and finallybrown in two minutes. The reaction mixture was heated at 50 C and stirred until completeconsumption of the aryl iodide was observed (tlc, 2 h). After filtering the crude material over a padof silica (5 g) and evaporation of the solvent the crude material (1H-NMR) was purified by silica column chromatography (eluent 10% EtOAc in pentanes, Rf = 0.41). After removal of the volatiles,the desired hydroxyl product was typically isolated as yellow oil with a purity > 98% (by 1H-NMR)and was used directly in the next step. Copies of NMR spectra are provided in the electronicsupplementary information.
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, 4-Iodobenzotrifluoride, other downstream synthetic routes, hurry up and to see.
