Synthesis of Some New Phenolic Azo Schiff Bases-Part I

摘要

p-Nitroaniline on diazotisation gives p-nitrobenzene diazonium chloride (I) which on condensation with salicylaldehyde gives 2-hydroxy-5-(4-nitrophenylazo) benzaldehyde (II). The compound (II) on condensation with substituted aniline gives 2-hydroxy-5-(4-nitrophenyl azo) benzylidine substituted aniline,i.e., substituted phenolic azo Schiff bases.
