Olefin metathesis is an organic in any of the pairwise mechanisms with olefin pairing which proved to be less sensitive to oxygen and water and. This invention provides a composition comprising (a) a catalyst and (b) a solubilizing agent, wherein the catalyst is utilized in a metathesis reaction.
Olefin metathesis is now a well-entrenched synthetic technique, and is a powerful method for the clean construction of innumerable classes of chemical architectures. Grubbs and co-workers led the development of ruthenium olefin metathesis catalysts and recognized that the catalytic ruthenium species were actually water-tolerant. “click” and olefin metathesis chemistry in water at room temperature enabled by biodegradable micelles. Olefin metathesis has emerged as one of the most widely used transformations in organic synthesis for the formation of carbon-carbon double bonds.
