Mix in water and then stir. That is all that is required in this new approach to stereoselective sp3−sp2 cross-couplings between an alkyl and alkenyl halide. Prior formation of organozinc reagents is not required.

prepared as an effective nanomicelle-forming species for general use in metal-catalyzed cross-coupling reactions in water. Several “name” reactions, including Heck, Suzuki−Miyaura, Sonogashira, and Negishi-like couplings, have been studied using this technology, as have aminations, C−H activations, and olefin metathesis reactions. Physical data in the form of DLS and cryo-TEM measurements suggest that
