The Zweifel reaction is a powerful transition-metal-free alternative to the Suzuki-Miyaura reaction for the synthesis of alkenes. This transition-metal-free coupling process enables the coupling of Grignard reagents or organolithiums for an enantiospecific synthesis of a wide variety of functionalized acyclic and cyclic olefin products.
