Electric Literature of 444-29-1, 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. 444-29-1, name is 1-Iodo-2-(trifluoromethyl)benzene belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: Pd(OAc)2 (22.4 mg, 0.10 mmol, 0.1 equiv), Ph3P (57.6 mg, 0.22, 0.22 equiv), and Cs2CO3 (1.63 g, 5 mmol, 5 equiv) were added to a flamedried, sealable vial under argon. Dry, degassed MeCN or DMF (3 mL) was added and the yellow mixture was stirred under argon for approximately 5 min. Aryl iodide (1.00 mmol, 1 equiv), alkyl iodide (10.00 mmol, 10 equiv), and olefin (5.00 mmol, 5 equiv) were added successively to the reaction mixture under argon. The mixture was stirred for 5 min, then solid norbornene (470 mg, 5.00 mmol, 5 equiv) was added. After a final argon purge, the vial was capped and placed in an oil bath that had been preheated to 90 °C. After 4?10 h, the mixture was cooled to r.t. Reactions performed in MeCN were filtered over a short pad of Celite (eluting with CH2Cl2) and concentrated in vacuo. Reactions performed in DMF were diluted with EtOAc? hexanes (1:1) and washed with brine twice. After drying with MgSO4, the organic layer was filtered and concentrated. The crude products were purified by flash column chromatography (CH2Cl2?hexanes, 1:5, then Et2O?hexanes, 1:100?1:25).
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-Iodo-2-(trifluoromethyl)benzene, other downstream synthetic routes, hurry up and to see.
