The olefin metathesis reaction of two unsaturated substrates is one of the most powerful carbon-carbon-bond-forming reactions in organic chemistry. When organic chemists want to construct six-membered carbon rings, their go-to method is that old stalwart, the diels-alder reaction but when they want to make five.
