Microwave-assisted Synthesis of Some New N, N`-Bis-[(2-hydroxy- napthalene-1-yl) Substituted Phenyl-methyl] 4,4`-diaminodiphenyl- Sulphone

An efficient and easy approach to N,N`-Bis-[(2-hydroxy-napthalene-1-yl) substituted phenylmethyl] 4,4`-diamine diphenyl sulphone derivatives is presented in this study. The products can be obtained both through the traditional method and via the microwave assisted protocol from the condensation of 4,4`-diamine diphenyl sulphone, benzaldehydes derivatives and β-naphthol. The characterization of the newly provided compounds elucidated by spectral methods: FT-IR, 1 H-NMR, 13 C-NMR, and Mass spectral data. Finally, the bis-Bestti bases have been screened for antimicrobial and antifungal activities. Keyword: Bis-Betti Base, 2-Naphthol, Microwave, One-Pot Reaction, Aromatic Aldehydes.
