Without using any toxic or hazardous reagent, ligand, acid, transition metal catalyst, additives/promoters and organic solvent, green Knoevenagel condensation and tandem Knoevenagel-Michael reactions have been successfully carried out by using chickpea leaf exudates as a naturally sourced Bronsted acid type bio-catalyst. The reaction proceeds in neat chickpea leaf exudates at room temperature i...

Reaction of Ni(0) in the presence of iodoarylethers leads, after syn intramolecular carbonickelation of the triple bond, to nucleophilic vinylnickels which can be trapped, in a tandem process, by various electrophiles introduced at the onset of the reaction.

Functional and condensed derivatives of 1,2,4-triazoles are mostly used as biologically active compounds, modern studies increasingly report their successful use surfactants, stabilizers for the formation nanoparticles, components hybrid perovskites, which promising materials opto-electronics.
