Abstract
Abstract 2-Hydroxy-1,4-naphthaquinone reacted with N(4)-ethylthiosemicarbazide in basic solution forms the 1-thiosemicarbazone. The crystal structure shows that the 2-hydroxy hydrogen is shifted to the remaining quinone oxygen resulting in the formation of a dimer due to intermolecular hydrogen bonding from each hydroxy group to the other molecule's quinone oxygen. Intramolecular hydrogen bonding occurs between the amide NH and the imine thiosemicarbazone moiety, as well as between the hydrazinic NH and the quinone oxygen. This new compound's IR, UV and 1H NMR spectra are included.
