A Direct Synthesis of N,N'-Bis(2-hydroxybenzylidene)-1,1-diaminoalkanes by a Three-Component Reaction

Article abstract of DOI:10.1055/s-1989-27236

The direct synthesis of new double Schiff bases with an alkane-1,1-diamine unit is achieved in good yields through a three-component reaction of salicylaldehyde or 5-bromosalicylaldehyde, aliphatic aldehydes, and ammonium acetate or aqueous ammonia in met
