ABSTRACT:
Ketones having at least one hydrogen atom or ester group in the .alpha.-position with respect to a ketonic carbonyl group thereof, for example cyclopentanone, 2-methylcyclopentanone and other substituted cyclopentanones, are effectively C- or .alpha.-alkylated, especially on an industrial scale, by reacting same with an alkylating agent in the presence of a catalytically effective amount of a condensed or uncondensed orthophosphate anion.
