Structure of the Coupling Products of Β-Phenyl Ethylidine M Alono-Nitrile With Benzene-Diazonium Chloride as Evidenced from its Polarographtc Reduction
Reda M. Khalfil
Abstract:
The polarographic behaviour of compound I. II, III have bean investigated in ethanolic buffer solution covering a pH range 2-12. Compound I showed two waves assigned to reduction of the hydrazone linkage and the olefinice>C=C< bond. The polorgrams of II showed three interfering waves for azo/hydrazone and >C=C< bond .In contrast afiover the whole pH range of study, compound III showed well defined 4e wave for reductfve cleavage of an azo group linked to hetaroatomic system. The obtained data was ueed to establish a hydrazone structure for compound I, II, teutomerism in azo farm was ruled out. Consequently, coupling products of ethylidine malononitrile with arytldteonum il tie hydrazone form and not in the cyclic pyridazine one.
Keywords:polarographic; arytldteonum; ethanolic hydrazone
