Abstract: 1,2-dibromo-4-(1,2-dibromoethyl)cyclohexane (TBECH), as an emerging brominated flame retardant (EBFR) pollutant, has been often observed in the air, and to comprehend its fate in the environment is still challenging due to the diversity of its stereoisomers.…

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…

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…
