It also covers the preparation of bromine and iodine, highlighting their solubility and reactions with metals and other compounds. The halogens are compared based on their reactivity, with ...

A new light-activated catalyst breaks and resets carbon–halogen bonds to convert racemic mixtures into enantiomerically ...
