A comparison of the reaction of the potassium and cesium phenolates of a series of peri-hydroxylated 9,10-anthracenediones with a range of alkylating agents is described. Cesium phenolates promote accelerated reaction rates, give higher product yields, and provide for the introduction of a wider range of alkyl groups.
