Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 955959-84-9, name is 4-(4-Bromophenyl)dibenzo[b,d]furan, A new synthetic method of this compound is introduced below., Application In Synthesis of 4-(4-Bromophenyl)dibenzo[b,d]furan
Preparation of compound C-6-2 [135] After dissolving compound C-6-1 (17 g, 52.6 mmol) in THF (400 ml), and adding 2.5 M n-BuLi in hexane (31.5 ml, 78.9 mmol) to the reaction mixture in -78°C, the reaction mixture was stirred for 1 hour. The reaction mixture was stirred for 12 hours with adding B(Oi-Pr) (24.1 ml, 105.2 mmol) slowly to the reaction mixture. After terminating the reaction, purified water 20 mL was dropped slowly to the reaction mixture. The reaction mixture was extracted with EA/NH4Cl aqueous solution. The obtained organic layer was concentrated, was triturated with MC/hexane, and then was filtered to obtain compound C-6-2 (14.5 g, 96 percent).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
