Process for the separation of 4-bromomethyl-2'-substituted biphenyls from 4,4,-dibromomethyl-2'-substituted biphenyls |
| abstract |
Disclosed herein is process for the separation of 4-bromomethyl-2'-substituted biphenyls of Formula (II) from 4,4-dibromomethyl-2'-substituted biphenyls of Formula (III) and 4-methyl-2'-substituted biphenyl of Formula (I) by stirring a crude reaction mixture comprising compounds of Formula (I), (II) and (III) in suitable organic solvents at a temperature above 50°C; and gradually cooling the reaction mixture below 20°C to obtain pure crystals of Formula (II) with purity of more than 97%. |
