Protocol for olefin metathesis reactions of hydrophobic substrates performed in aqueous emulsion with mechanical stirring or with microwaves support

In the presented protocol, we describe the olefin metathesis of hydrophobic sub-strates in water emulsions using ruthenium catalysts in the presence of air. Wedetail the testing of mechanical foaming for emulsification and the use of micro-wave heating to optimize metathesis reaction efficiency. By utilizing relatively low catalyst loading and ensuring simple product isolation, the steps outlined in this protocol extend known methods for the aqueous metathesis techniques.
