Abstract: 2-Amino-4-arylbuta-1,3-diene-1,1,3-tricarbonitriles obtained by Knoevenagel condensation between aldehydes and malononitrile dimer reacted with cyanoacetohydrazide in the presence of bases to afford N’-arylidene-2-cyanoacethydrazides instead of

We tried to obtain 4-cyano 5-aryl pyrazolidones-(3) 3a, b and related azomethine imines 4a, b.However the reaction of α-cyano β-aryl acrylic acid ethylesters 2a, b with hydrazine yields the familiar cyano acetic acid arylidene hydrazides 5a, b by cleavage
