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.
