Abstract

An olefin metathesis/double bond migration sequence of allyl ethers to cyclic enol ethers is catalyzed by first and second generation Grubbs' catalysts. These ruthenium carbene complexes were activated to catalyze the double bond migration by additioin of hydride sources, such as NaH or NaBH₄.
