Structural and spectral characterization of two bis{N(4)-alkylthiosemicarbazones} of 1-phenylglyoxal
摘要:
The 1-phenylglyoxal bis {N(4)-methyl- and {N(4)-ethylthiosemicarbazones}, H(2)Pg4M and H(2)Pg4E, have been prepared, studied spectroscopically (H-1 NMR, ultraviolet and infrared) and their crystal structures solved, Intramolecular hydrogen bonding connects the two thiosemicarbazone moieties in both H(2)Pg4M and H(2)Pg4E such that they are on the same side of the carbon-carbon backbone, and N(4)H hydrogen bonds to the azomethine nitrogen for each moiety.
