Abstract:
In search of some antimicrobial agents, synthesis of some Schiff base of cyanoacetohydrazide derivatives has been reported. The structures of all the synthesized compounds were established on the bases of various spectroscopic methods. All Schiff base were screened for antimicrobial activity. cyanoacetohydrazide were found to possess better antimicrobial potential.

Abstract:
A cyanoacetohydrazide derivative underwent a series of reactions with different nucleophilic reagents, such as hydrazine hydrate, p-chlorobenzaldehyde and salicylaldehyde, to give the condensation products. In addition, an arylidene malononitrile was reacted with different nitrogen nucleophiles, such as hydrazine hydrate, thiocarbohydrazide and cyanoacetohydrazide, to afford the hydrazine, hydrazone and pyridin-2-one derivatives, respectively. Furthermore, a pyridin-2-one derivative was reacted with different carbon electrophiles, such as carbon disulfide, p-chlorobenzaldehyde and acetic anhyd

Abstract:
AbstractNew cyanothioformamide derivative 1 was prepared by treatment of 3,5-dichlorophenyl isothiocyanate with potassium cyanide at room temperature. Cycloaddition of cyanothioformamide 1 with phenyl isocyanate as electrophile furnished the corresponding imidazolidine 2. Imine hydrolysis of 2 with ethanolic HCl produced the corresponding 4-thioxo-2,5-imidazolidinedione 3. This compound was used as key synthon for the preparation of a wide variety of new substituted imidazole compounds. Condensation of 3 with different types of hydrazine derivatives furnished new series of hydrazone 4a, b, thi
