The Divergent Reactivity of Acid Chlorides Under Transition Metal Catalysis

The power and ability of catalysis to build multiple C-C bonds in a single step has had a transformative impact on organic synthesis. While the reactivity of organohalides with metal catalysts is widely appreciated, the related and more intricate reactivity of acid chlorides is less so, despite their use as common reagents in synthesis. Here, we review the transformations of acid chlorides in combination with unsaturated C-C bonds catalyzed by palladium, rhodium, or iridium and provide an outlook for future research opportunities.
