preparations of naphthazarin, and 2-methylnaphthazarin have been found to give by-products, which have been identified. 5,8-Dihydroxy-1,3-dimethylnaphtho[2,3-c]furan-4,9-quinone has been synthesised, and its chemistry is described; 2-bromomethylnaphthazarin diacetate has also been obtained. Nuclear magnetic resonance measurements are reported for the naphthoquinones, their precursors, and derivatives.
