Conventional and Microwave Irradiated Syntheses of New Symmetric Double Schiff Bases of 1,1’-Bis(4-Amino Phenyl)Cyclohexane, their Spectral Characterization and Microbial Activity

Abstract

Symmetric double Schiff bases of 1,1’- bis (4-amino phenyl) cyclohexane and substituted aromatic benzaldehydes were synthesized by thermal and microwave irradiated green chemistry techniques. The purity of Schiff bases was checked by TLC. The structure of Schiff bases were supported by UV, FTIR, 1HNMR and MS techniques. The antibacterial and antifungal activities of Schiff bases were checked against gram positive and gram negative microbes. Schiff bases showed moderate antibacterial activity but they showed good comparable antifungal activity against chosen microbes and standard drugs.
