Nucleophilic attack of anthraisoxazol-6-ones, and of anthraisoxazole by various sulfoxides, triphenyl phosphine, and aliphatic or aromatic phosphites proceeded with cleavage of the nitrogen-oxygen bond of the isoxazole ring.This method provided ready access to substituted anthraquinones bearing sulfoximido-, triphenylphosphazo-, and dialkyl(aryl)phosphoramidic groups attached to the 1- and the 1,5-positions of the anthraquinone system.The structures of the newly synthesized anthraquinone derivatives were supported by analytical and spectral data. 1 -S,S-dimethyl-N-(5-benzamidoanthraquinon-1-yl)sulfoximide yielded in 90percent sulfuric acid the 1-amino-5-sulfoximido anthraquinone without hydrolyzing the sulfoximido group.
