Formazans was first synthesized over a century ago, but still attract attention of chemists,
biologists, technologists and other specialists. In recent years, antiviral, anti-inflammatory …

In this study, formazans 5a–5h were synthesized by coupling the reactions of substituted
phenylhydrazone compounds 3a–3h with diazonium salt of 4-chloro-2 …

Graphitic carbon nitride (gC 3 N 4) was synthesized by melamine and functionalized by H 2
SO 4 treatment using ultrasound assisted method. As prepared functional carbon nitride (Sg …

A series of novel formazan analogs 4 a–e, having MeO, Me, Cl, NO2 at para/meta‐position
in 1‐phenyl ring was synthesized by treatment of 9‐fluorenone hydrazone 2 with a series of …

A series of phenylsulfanyl and aryl carbonyl containing formazan derivatives 4a–4h and 5a–
5h were synthesized by coupling of substituted phenylhydrazones with diazonium salts of 2 …

In the present research, a series of 3-(4-chloro phenyl)-1-nitro phenyl-5-(substituted phenyl)-
formazans (5a-d) were synthesized by the condensation of schiff base (3) and diazonium …

Research in heterocyclic chemistry has gained momentum in recent times because more
than half of the biologically active molecules belong to various classes of heterocycles1 …

In this study, formazans 5a− 5h were synthesized by coupling reactions of substituted
phenylhydrazone compounds 3a− 3h with diazonium salt of 4-chloro-2 …
