Synthesizing n(4)-substituted thiosemicarbazones and their structural characteristics

Abstract

Some thiosemicarbazones such as 4-nitrobenzaldehyde-[N(4)-methyl, N(4)-phenyl thiosemicarbazone] (L1), Fluoren-9-one-[N(4)-(4-methylpiperidyl) thiosemicarbazone] (L2) and 4’-hydroxyacetophenone-[N(4)-(4-methylpiperidyl) thiosemicarbazone] (L3) were  prepared by the classical method. Their components and structures were determined by the spectra of IR, UV-Vis, ¹H-NMR,¹³C-NMR, COSY, HSQC, HRMS. According to the results of SciFinder at KU Leuven (Belgium) on December 19^th 2014, the structures of L2 and L3 have not been reported in any scientific studies.
