Web10. okt 2024 · Schiff bases can act as ligands and chelate with metals by using imine nitrogen and the functional groups which are commonly associated with aldehyde counterparts. 47 ... Mohan et al. synthesized four highly fluorescent Schiff bases 1a-d by condensing 4,5-dimethyl-1,2-phenylenediamine with different aldehydes such as N-ethyl-3 ... Webbase ligands have several applications, including catalytic activities.7a,10 Moreover, the unsymmetri-cally substituted metal-Schiff base complexes are found to have better catalytic activities towards Suzuki-Miyaura cross-coupling reactions8 and others.11 Unsymmetrically substituted Schiff base creates lower steric crowding around the metal Webo-Phenylenediamine a weak aromatic amine base neutralizes acids in exothermic reactions to form salts. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides.
