Abstract
A series of 1-benzothiazoLyl-3,5-diphenylformazans with substituents in the 6-position of the benzothiazole ring were synthesized. The introduction of halogens and methyl and alkoxy groups into this position induces deepening of the color of the corresponding formazans as compared with the unsubstituted benzothiazolyldiphenylformazan. Benzothiazolylazo- and 6-methylbenzothiazolylazophenylhydrazones of benzaldehyde were isolated along with formazans in the coupling of benzothiazolinediazonium and 6-methylbenzothiazolinediazonium sulfates with benzaldehyde phenylhydrazone.
