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
In one embodiment, the present application discloses mixtures comprising (a) water in an amount of at least 1% wt/wt of the mixture; (b) a transition metal catalyst; and (c) one or more solubilizing agents; and methods for using such mixtures for performing transition metal mediated bond formation reactions.
