AbstractA green, efficient, and rapid procedure for the synthesis of N,N′-arylidene bisamide derivatives has been developed by one-pot condensation of aldehydes and amides in the presence of tris(hydrogensulfato)boron as a highly effective heterogeneous catalystundersolvent-freeconditions at 100 °C. Various aromatic aldehydes, acetamide or benzamide were used in the reaction, and in all cases the
