Hydrazines et hydrazones heterocycliques. III. Synthese de derives du naphto[2,3-d]thiazole

The synthesis of 2-hydrazinonaphtho2,3-d]thiazole, 3-methylnaphtho-2,3-d]thiazolin-2-one hydrazone and some of the corresponding 2-alkylidenehydrazino-3-methylnaphtho2,3-d]thiazoles is described. These compounds have been characterized by their infrared, ultraviolet, nmr spectra in the presence of Eu(fod)₃ and by their mass spectra.
