Aspecte de sinteză a unor derivaţi ai 4-(2,4,6-trimetilfenil)-semicarbazidei [Articol]

Abstract

The dissertation is dedicated to the synthesis, determination of composition, physical properties of some trimethylphenylsemicarbazones. As an initial substance was used isocyanato-2,4,6-trimethylbenzyene. It was submitted to interaction with hydrazine hydrate and respectively condensation with salicylic aldehyde, 8-quinoline aldehyde, pyridine-2-carbaldehyde, 1H-indole-2,3-dione. Semicarbazones, semicarbazides and their heterocyclic derivates often present biological activity properties and they can be used in: medicine, agriculture, technique, and analytical, inorganic, organic chemistry.
