Abstract
MY attention has been directed to a paper in the August (1927) issue of the Journal of the American Chemical Society (p. 2043), in which Stauder and Adams have shown that rubiadin is not 1,3-dihydroxy-4-methylanthraquinone. It is of interest to record that we came to the same conclusion by condensing cresorsellinic acid with benzoic acid in presence of sulphuric acid.
