445-26-1, 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. 445-26-1, name is 1-(2-Fluorophenyl)ethanol, the common compound, a new synthetic route is introduced below.
Intermediate 1-17-1 Preparation of 1 -(1 -bromoethyl)-2-fluorobenzene 500 mg 1 -(2-Fluorophenyl)ethanol (3.6 mmol, 1 .0 eq.) was dissolved in 1 .6 mL hydrobromicacid (33% solution in acetic acid, 9.8 mmol, 2.8 eq.) and stirred at room temperature over night. The reaction mixture was poured into diethylether and stirred for 5 min. The solution was added portionwise into 30 mL of saturated sodium hydrogen carbonate solution and stirred for 15 min. The layers were separated and the aqueous layer was extracted with diethylether twice. The collected organic layers were rinsed with brine, dried over a silicon filter and concentrated in vacuo. The crude product was used without further purification: 554 mg, 2.73 mmol, 77%. 1 H NMR (300 MHz, DMSO-d6) delta [ppm] = 1 .98 (d, 3H), 5.57 (q, 1 H), 7.13 – 7.24 (m, 2H), 7.31 – 7.41 (m, 1 H), 7.56 – 7.65 (m, 1 H).
Statistics shows that 445-26-1 is playing an increasingly important role. we look forward to future research findings about 1-(2-Fluorophenyl)ethanol.
