epa chemical information [1,1'-biphenyl] - 3-methanol, 2-methyl- (76350-90-8)

biphenyl alcohol use and synthesis method

chemical properties this product is white crystal, m.p.73 ~ 76 ℃, soluble in ethanol, benzene, toluene and other organic solvents, insoluble in water.

use 2-methyl- (1,1'-biphenyl) -3-methanol is an insecticide bifenthrin intermediates.

production methods 2 - methyl - (1,1'-biphenyl) -3-methanol is a 3-chloro-2-methyl-biphenyl and magnesium metal reaction grignard reagent, and then with polyoxymethylene diacetate reaction get the product

after adding 3-chloro-2-methylbiphenyl and tetrahydrofuran to the reactor, adding fresh metallic magnesium and recovered metallic magnesium for refluxing for 5 hours, adding polyacetal diacetate and continuing to reflux for several hours, after cooling, treatment, distillation products, yield up to 70.8%.

in addition, 3-chloro-2-methylbiphenyl can also be used as a raw material to react with cuprous cyanide in the presence of pyridine to generate 3-cyano-2-methylbiphenyl, and first reduction to obtain 2-methyl- 3-formaldehyde, and further reduced to 2-methyl - (1,1'-biphenyl) -3-methanol.

can also be 2-methyl-3-nitrobenzyl alcohol as the raw material, the first hydrogenation to 2-methyl-3-aminobenzenemethanol, sodium nitrite, potassium iodide and copper powder in the presence of sander mayer reaction to generate 3-iodo-2-methylbenzyl alcohol, which is then reacted with benzene in a photoreactor under uv light irradiation to produce 2-methyl (1,1'-biphenyl) -3-methanol. see the reaction equation to see figure:
