Indole heterocycles have an established reactivity, and these compounds are H-bond donors via a peculiar non-basic NH. However, the indole core has been scarcely employed in organocatalysis, with only a few examples relevant to electrophilic halogenation reported. To expand the r...

This study describes the efficient synthesis of five dinitrochalcones (DNCHs) using an ultrasonic bath as an unconventional method to improve reaction yields and reduce reaction times. The Claisen–Schmidt condensation of nitroacetophenones and nitrobenzaldehydes was carried out i...
A graft reaction of polyvinyl chloride (PVC) with furfural was conducted in a tetrahydrofuran solution. The resulting graft structure (FF-g-PVC) was characterized using UV spectroscopy, photoluminescence (PL), Fourier Transform Infrared (FTIR) spectroscopy, Raman spectroscopy, an...

The commercial flame-retardant 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) was almost quantitatively converted in sodium [2-(2-hydroxyphenyl)phenyl]phosphinate Na[OH-Ph-Ph-PHO2] and disodium 2-(2-phosphinatophenyl)benzen-1-olate Na2[O-Ph-Ph-PHO2] under mild reaction...
Six secondary amine derivatives derived from salicylaldehyde (SA) were successfully synthesized in good to excellent yields and evaluated for their biological activities. The synthesized compounds exhibited remarkable antioxidant properties, as determined by ABTS and phenanthroli...
