Abstract
Addition of small percentages of the nonionic, vitamin E-based amphiphile “PTS” allows unsymmetrical, E-selective olefin cross-metathesis reactions in water, involving water-insoluble substrates, at room temperature using commercially available catalysts. The nanometer micelles formed accommodate water-insoluble substrates, along with a readily available Ru-based metathesis catalyst.
