Abstract
Coupling p-tolyldiazonium salts with hydrazones of 2-hydrazinonaphth-[1,2-d]thiazole gives the unsymmetrical 1-napth[1, 2-d]thiazolyl-3-aryl(or methyl]-5-p-totylformazans. Conclusions concerning their structure are drawn on the basis of the IR and UV spectral data, and comparisons are made with the isomeric naphth[2, 1-d]thiazole formazans.
