1,8-diazabicyclo[5.4.0]undec-7-ene-promoted regioselective elimination of vicinal dibromides having an adjacent O-and/or N-functional group
We have investigated the DBU-promoted HBr-elimination of vicinal dibromides having an adjacent O- and/or N-functional group under mild basic conditions. The elimination of 1-oxygenfunctionalized 2,3-dibromopropanes was more regioselective than that of 1-n
