An efficient route for the Knoevenagel condensation of aromatic aldehydes with barbituric acids and 2-thiobarbituric acids in the presence of polyvinyl pyrrolidone (PVP) stabilized Ni nanoparticles in ethylene glycol has been reported. A range of biologically important arylidene barbiturates were obtained in high yields (82-97%) in a very short reaction time. Graphical Abstract: A novel and highly efficient PVP-stabilized Ni nanoparticles catalyzed synthesis of arylidene barbiturates and arylidene 2-thiobarbiturates has been described.
