A suspension of biphenyl-4-yimethanol (36.8 g, 200 mmol) in dichloromethane (240 mL) was treated with 50% aqueous potassium hydroxide solution (160 mL). The reaction mixture was cooled to 0″C, and maintained at 0 – 1OC as tetra-rt-butylammonium sulfate (1.18 g, 2,0 mmol) was added, followed by a slow addition of trichtoroacetonitrile (25.1 mL, 250 mmol) over 10 minutes. The reaction was stirred at OC for an hour, and then stirred at 25C for an additional hour, after which the organic layer was filtered through a short pad of Celite on top of a layer of silica gel. The pad was rinsed with additional methylene chloride (1500 mL), and the elubetants were concentrated in vacuo to provide C93 as a white solid, which was used in the next step without purification. Yield: 66.1 g, quantitative. LCMS m/z 167.2 (C13H1 1′). 1H NMR (400 MHz, CDCI3) 6 5.40 (s, 2H), 7,37 (m, 1 H), 7.46 (m, 2H), 7.52 (d, J?8.7 Hz, 2H), 7,62 (m, 4H), 8.43 (br s, 1 H).

Adding a certain compound to certain chemical reactions, such as: 3597-91-9, [1,1′-Biphenyl]-4-ylmethanol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: 3597-91-9, blongs to alcohols-buliding-blocks compound. Recommanded Product: 3597-91-9

General procedure: Mixture of 0.005 g and glacial acetic acid was placed in a 50-mL round bottom flask, and was stirred for 5 min. Then, alcohol(1 mmol) was added to the solution, and reaction solution was stirred under reflux condition for specified time. The progress of reaction was monitored by TLC (acetone-n-hexane, 1 : 2). After completion of the reaction, catalyst was easily removed by shutting down the stirrer without using any external magnet. The product was purified by recrystallizationin hot ethanol. For the reaction times andthe structures and yields of the products, see Table 2.
