Synthesis and cyclisation of 1,4-disubstituted semicarbazides

Semicarbazides, besides possessing medicinal properties, also find wide applications in agriculture and industry. We report in this article the synthesis of the four 1,4-disubstituted semicarbazides: 1-cinnamoyl-4-phenyl semicarbazide (1), 1-oleyl-4-phenyl semicarbazides (2), 1,1',1''-tricitryl-4,4', 4''-triphenyl semicarbazide (3) and 1-benzoyl-4-phenyl semicarbazide (4), by the condensation of four different hydrazides: cinnamic acid hydrazide (5), oleic acid hydrazide (6), citric acid hydrazide (7) and benzoic acid hydrazide (8). The acid hydrazides were prepared by the condensation of four different acids with phenyl isocyanate. The semicarbazides were also subjected to acid catalysed intramolecular cyclisation. The cyclisation of (1) and (2) afforded substituted 1,3,4-oxadizoles: 2-cinnamoyl-5-aminophenyl 1,3,4-oxadizoles (9) and 2-oleyl-5-aminophenl 1,3,4-oxadizoles (10), respectively, in high yield, while no cyclisation occurred in the cases of (3) and (4). The products in each case have been identified on the basis of melting points and IR spectral studies.

Corrosion Inhibition and Electrical Properties of 4-Phenyl-1-cinnamoylsemicarbazide (HPCS)

Matal complexes of 4-phenyl-1-cinnamoylsemicarbazide with Co(II), Ni(II) and Cd(II) ions were prepared.The electrical conductivities of these compounds have been measured in the temperature range 27-152 deg C.The positive temperature coefficient (d?/dT) o

Coordination complexes derived from 1-cinnamoyl-4-phenylsemicarbazide (HCPS)

A number of new complexes of the transition metal ions, Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II), with 1-cinnamoyl-4-phenylsemicarbazide (HCPS) have been synthesized.Attempts have been made to ascertain their probable structures on the basis of e
