Check out Kevin and Joanne’s paper using iron catalysts for Heck cross-coupling between styrenes and functionalised alkyl bromides. Yields up to 93% and especially useful for alkenylation of functionalised tertiary alkyl halides typically difficult to target by classic palladium-catalysed Heck reactions.
