Abstract
1-Nitroso-2-naphthol and 2-nitroso-1-naphthol, both in the isonitroso form, react with benzyl bromides in THF and in the presence of triethylamine affording, in low yields, the corresponding O-benzyl oximes and 2-aryl naphthoxazoles in a 1:1 ratio, approximately. The structures of O-benzyl oximes and naphthoxazoles isolated have been determined by X-ray analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
