Abstract: Abstract (Z)-4-(2-(3,5-dibromo-2-hydroxy-4-methoxybenzylidene)hydrazinyl)benzonitrile compound (DHMB) was synthesized by a condensation reaction of 4-cyanophenylhydrazine hydrochloride and 3,5-dibromo-2-hydroxy-4-methoxy benzaldehyde. For characterization of DHMB were used IR, UV visible, LC-MS NMR devices. Kamlet-Taft and Catalan parameters were computed from… read more here.

DOI: 10.1039/c7qo00287d
Abstract: Treatment of Δ1-dipyrrolines with NBS afforded α,α′-dibromo-Δ1-bipyrrolines and α,α,α′,α′-tetrabromo-Δ1-bipyrrolines respectively with excellent selectivity depending on the amount of NBS. All these multibromo-substituted Δ1-bipyrrolines could be efficiently transformed into their corresponding 2,6-diazasemibullvalene derivatives via reduction with… read more here.
