Zg. Aliev et al., REACTIONS OF AROYLPYRUVIC ACIDS WITH S-METHYLISOTHIOSEMICARBAZIDE HYDROIODIDE AND STUDIES OF THE CRYSTAL-STRUCTURES OF THE REACTION-PRODUCTS, Russian chemical bulletin, 47(4), 1998, pp. 682-686
The reactions of p-chlorobenzoyl- and benzoylpyruvic acids with S-meth
ylisothio-semicarbazide hydroiodide gave (p-chlorophenacyl)-2,5-dihydr
o-1,2,4-triazin-5-one and nacyl-2,3,4,5-tetrahydro-1,2,4-triazine-3,5-
dione, respectively. The molecular and crystal structures of the compo
unds synthesized were studied by X-ray diffraction analysis.
