Parham cyclization bromoaromatic carboxylic acids

The well-known Parham cyclization of bromoaromatic carboxylic acid derivatives can be exemplified by the examples in equations (27)-(29). The reaction is usually run at very low temperature in ether or llIF and provides surprisingly good yields of aromatic ketones. The method has been reviewed recently. ...
