“…In the past 12 years a number of innovations and new techniques have been reported, including solvent-free/clay/microwave irradiation, solid-state synthesis, K-10/microwave, water suspension medium, [bmim]BF 4 /molecular sieves, infrared irradiation/no solvent, NaHSO 4 AESiO 2 /microwave/solventfree, solvent-free/CaO/microwave, and silica/ultrasound irradiation [25][26][27][28][29][30][31][32][33]. Among these innovations, microwave irradiation has been extensively used due to its operational simplicity, enhanced reaction rates, and great selectivity [32].…”

Schiff bases are aldehyde-or ketone-like compounds in which the carbonyl group is replaced by an imine or azomethine group. They are widely used for industrial purposes and also exhibit a broad range of biological activities. This short review compiles examples of the most promising antimalarial, antibacterial, antifungal, and antiviral Schiff bases. An overview of synthetic methodologies used for the preparation of Schiff bases is also described.

“…In other words, when the substrate bears an electron-withdrawing group, a more efficient conversion took place. Moreover, an electron-releasing group on the aniline ring improves the yields ( Scheme 8 and Scheme 9 ) [ 17 , 18 ].…”

This review provides a comprehensive overview of where infrared irradiation has been employed, mainly as regards activating green mode for natural products extractions, as well as to favor a reaction, highlighting its actual importance. It is also underlined that infrared irradiation heating has been around for a long time; however, only in the last eighteen years have many of its advantages been applied to satisfy a wide range of chemical processes, natural products extractions, and for the promotion of many kinds of reactions. In addition, it is brought to light that near infrared irradiation is more efficient than middle and far infrared irradiations, being easily controllable and with the quality of a fast responding heat source. Thus, the main objective of this review is to offer infrared irradiation as an alternative clean energy source to activate reactions, in addition to favor the selective extraction of natural products, all of which is within the Green Chemistry protocol. Some recent results from our laboratory are also included.

“…Compounds obtained from these reactions accompanied by Schiff bases have been used in the treatment of various diseases due to their biological activity [23]. Many reagents have been used for the synthesis of imines such as Lewis acids [24][25][26][27], metal complex [28,29], metal-free conditions [30,31], promoted by microwave irradiation [32] and ultrasound radiation [33].…”

Schiff bases (imines) have been frequently used in various fields such as medicine, pharmaceutical purposes due to their various biological properties. In this study, nine new imine compounds (3a-h) were synthesized from 1-naphthyl amine with aromatic aldehydes in MeOH and their chemical structures were defined by 1H/13C NMR, IR and elemental analysis studies. We observed a singlet one hydrogen of the imines (-CH=N-) at 8.56-8.86 ppm in the 1H NMR spectra and also carbon of the Schiff bases (-CH=N-) at 158.2-163.4 ppm in the 13C NMR spectra. Also the IR spectra displayed the (-C=N-) characteristic absorption band at around 1600 cm-1. The obtained characteristic peaks at the expected locations proved the structural accuracy of the synthesized new derivative Schiff bases.
