An efficient single-pot strategy for 2-amino nicotinonitrile derivatives 5 has been developed by multi-component reaction of arylaldehydes 1, methylketones 2, malononitrile 3, and ammonium acetate 4 using tetrabutyl ammonium bromide as catalyst in aqueous medium.

Abstract In this work, a diester cationicgeminisurfactant (DCGS) was prepared from the reaction of N,N-dimethyldodecylamine with the microwave (MW)-assisted synthesized spacer ethane-1,2-diyl bis(2-chloroacetate) (EDBC) by the three-component reaction of ethyleneglycol with chloroacetic acid (2 equiv.) under MW-irradiation. The structure of the spacer EDBC and surfactant DCGS were evaluated by 1H NMR
