Related Products of 811842-30-5, The chemical industry reduces the impact on the environment during synthesis 811842-30-5, name is 2-Bromo-1-fluoro-4-iodobenzene, I believe this compound will play a more active role in future production and life.
To a flask containing 2-bromo-1-fluoro-4-iodo-benzene (4.0 g, 13.3 mmol) and 1,4-dioxa-8-azaspiro[4.5]decane (2.09 g, 14.6 mmol) in N-methyl-2-pyffolidone (50 mL) was addedK2C03(3.67 g, 26.6 mmol), CuT (128 mg, 0.67 mmol) and L-proline (77 mg, 0.67 mmol) under N2. After being heated with stuffing at 120 C overnight, the resulting mixture was cooled to rt, diluted with H20 (50 mL) and extracted with EA (50 mL) for three times. The combined organic layer was washed with brine (50 mL), dried over anhydrous Na2SO4 and concentrated in vacuo.The residue was purified by flash chromatography to give 8-(3-bromo-4-fluoro-phenyl)-1,4- dioxa-8-azaspiro[4.5]decane (1.4 g).
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, 2-Bromo-1-fluoro-4-iodobenzene, other downstream synthetic routes, hurry up and to see.
