The reactions of 2-methyl-1,4-naphthoquinone with triethylaluminium and 2,5-di-t-butyl-1,4-benzoquinone with triisobutylaluminium were studied.In each of these reactions three different products were obtained and characterized by n.m.r. and i.r.U.V. spectrophotometry showed that 2-methyl-1,4-naphthoquinone behaves as a weak base and the ionization constants pK1 = -0.922 and pK2 = -4.065 were reported in aqueous HClO4.This is a useful information for elucidating the mechanism of the first reaction studied, based on the different basicity of the carbonyl groups.
