A convenient method for removing all highly-colored byproducts generated during olefin metathesis reactions
[formula: see text] Addition of a very modest amount of lead tetraacetate (1.50 equiv relative to the amount of Grubbs catalyst) to ring-closing metathesis reaction mixtures effectively removes all colored ruthenium and phosphine impurities to deliver colories reaction products.
