| titleOfInvention | Production of 4,4'-dialkoxybiphenyl |
| abstract | PURPOSE: To contrive improvement in reaction rate, by the coexistence of a specific compound, such as β-diketone, in a reaction system in producing the title compound from 4,4'-dibromobiphenyl and a metal alkoxide using a specific mixed solvent and copper based catalyst. n CONSTITUTION: 4,4'-Dhibromobiphenyl is reacted with a compound expressed by the formula MOR (M is alkali metal; R is 1W15C alkyl, aralkyl or aromatic hydrocarbon group which may have a substituent group) in a mixed solvent of N,N-dimethylformamide and a compound expressed by the formula R'OH (R' has the same meaning as that of R) in the presence of a copper compound to produce the title compound useful as a raw material for biphenyl-4,4'-diol. In the process, a β-diketone compound, nitrogen-containing heterocyclic aromatic compound and/or aliphatic amine compound are present in the above-mentioned reaction system to improve reaction rate while maintaining high selectivity. Thereby the aimed compound is obtained from the afore-mentioned raw material readily producible from biphenyl in high yield for a short time. n COPYRIGHT: (C)1989,JPO&Japio |
