A stepwise mechanism for the reaction of 9-aryloxy-1,10-anthraquinones with alcohols has been established, starting with nucleophilic 1,4-addition of a molecule of alcohol.A quantitative reactivity study has been carried out.Introduction of acceptor substituents into the anthraquinone nucleus substantially increases the reaction rate, while donor substituents reduce it.A qualitative correlation between the rate constants and the electron density at the C and O atoms of the reaction site has been established.
