Method for the selective alpha halogenation of alkylaromatic compounds |
| abstract |
Inorganic and organic hypohalites are used to obtain good selectivity to alpha halogenation of alkyl aromatic compounds. Alkali and alkaline earth hypohalites must be used in conjunction with a phase transfer medium. Useful organic hypohalites are the tertiary alkyl hypohalites, which are employed in the presence of free radical generating media such as light or compounds which produce free radicals thermally. At least one mole of hypohalite reactant must be used for every alpha hydrogen in the alkyl aromatic compound. n A new bisphenol which contains biphenyl functionality has been made as well as an aromatic polyester derived therefrom. |
