Abstract
Procedure for the preparation of triazolyl-coumarins, which correspond to formula I, ** (see formula) ** (I) in which R1 means a lower alkyl group or a phenyl group optionally substituted in a non-chromogenic way, R2 means a lower alkyl group or a benzoidic aromatic radical, optionally substituted in a non-chromogenic way, and R3 means a phenyl group, optionally substituted in a non-chromogenic way, characterized in that compounds of formula II are reacted, ** (see formula) ** (II) with diazonium salts of formula III, ** (see formula) ** ** (see formula) ** (III) to form compounds of formula IV, ** (see formula) ** (IV) then it is reacted with hydrazines of formula V, R2 -NH-NH2 (V) and the oxime hydrazones originating from formula VI, ** (see formula) ** (VI) they condense in known manner to form triazoles of formula I.
