摘要 |
Rearrangement of alpha-halo-alkylarylketals in neutral or weakly alkaline conditions and in the presence of a polar-protic medium and subsequent hydrolysis of the thus obtained esters, in the same reaction medium, to afford the corresponding alpha-arylalkanoic acids or their salts which are particularly useful as anti-inflammatory, analgesic and antipyretic agents. |
