Cover Feature: trans-Cyclooctenes as Scavengers of Bromine Involved in Catalytic Bromination (Chem. Eur. J. 8/2024)
Graphical Abstract
A trans-cyclooctene (TCO) bearing a 2-pyridylethyl group has been developed to retard uncatalyzed bromination reactions using N-bromosuccinimide by capturing bromine generated in situ, which was revealed to cause background reactions. The TCO is useful as an additive for improving catalyst-controlled selectivity and as a probe to investigate the involvement of Br2 in catalytic bromination.
