Abstract
In this open ended experiment, students have to determine the identity of the brominated product when a coumarin is treated with N-bromosuccinimide (NBS). The product is purified via column chromatography and analyzed by NMR. The hydrogen of the alkene of the coumarin is replaced with a bromine instead of the bromine reacting with the aromatic ring.
