Synthetic Route of 7073-69-0, 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. 7073-69-0, name is 2-(2-Bromophenyl)propan-2-ol. A new synthetic method of this compound is introduced below.
General procedure: Using diaryl acetylenesA 5-mL two-necked flask equipped with a stir bar was charged with [RhCl(cod)]2 (0.0125 mmol,6.16 mg), BINAP (0.0125 mmol, 7.78 mg), 1a-c (0.25 mmol), KI (0.25 mmol, 41.5 mg), and Na2CO3(1.0 mmol, 106.0 mg). The central neck of the flask was equipped with a reflux condenser havinga N2 gas-bag (2 L), which was connected by a three-way stopcock at its top, and a rubber septumwas inserted i n to the side neck. The flask was evacuated and backfilled with N2 (three times).Xylene (1.0 mL), 2a (0.75 mmol, 161.3 mg), and furfural (1.75 mmol, 168.2 mg), were then added.After degassing the reaction mixture three times by the freeze-pump-thaw method, the flask wasfilled with N2. The mixture was placed in an oil bath that had been preheated to 140 C for 20 h.After cooling to room temperature, the resulting solution was filtered through a pad of celite, andthe filtrate was concentrated in vacuo. The resulting crude product was purified by flash columnchromatography on silica-gel to afford 3aa-3ac.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,7073-69-0, 2-(2-Bromophenyl)propan-2-ol, and friends who are interested can also refer to it.
