Synthesis and root growth activity of some new acetylhydrazinecarbothioamides and 1,2,4-triazoles substituted with 5H-dibenzo[a,d]annulene moiety [PDF]

Journal of the Serbian Chemical Society, 2012
New hydrazinecarbothioamides 5a-d bearing 5H-dibenzo[a,d]an-nulene moiety were synthesized using classical procedures. 1H-NMR analysis indicated the existence of two conformational isomers, a major axial (about 75%) and a minor equatorial one (25 ...
