Acridone studies. XI. Reaction of some Polyalkoxy-10-methylacridones with sodium methoxide in methanol and in dimethyl sulphoxide

Abstract

The isomeric dimethoxymethylenedioxy-10-methylacridone react with sodium methoxide in methanol to give a number of products which have been characterized. Substitution occurs on both the aromatic nucleus and the methylene group. In dimethyl sulphoxide opening of the methylenedioxy ring occurs exclusively and the rates and activation parameters of this reaction have been measured.
