Abstract
2-Cyano-N'-(9H-fluoren-9-ylidene)acetohydrazide was prepared from the readily obtainable cyanoethanoic acid hydrazide with 9-fluorenone. The title compound underwent a series of heterocyclization reactions through its reaction with different electrophilic reagents such as aromatic aldehydes, arylidene malononitrile, malononitrile, ethyl acetoacetate, phenyl isothiocyanate and CS 2 to give novel heterocyclic compounds. Moreover, its reaction with thioglycollic acid was also investigated. The spectral characterization (IR, 1 H NMR, MS) of the newly synthesized compounds were discussed.
