Abstract of US 5600013  (A)
Cyclic ketones, notably cyclopentanone and 2,2-dimethylcyclopentanone, are simply, economically and efficiently prepared, even on an industrial scale, by decarboxylating/cyclizing a dicarboxylic acid, in liquid phase, in the presence of a catalytically effective amount of a condensed or uncondensed neutral phosphate.
