Significance

Olefin cross-metathesis has found widespread use in bench-scale and process chemistry as a reliable way of forming carbon-­carbon double bonds (see Review below). With few exceptions, the more thermodynamically ­favored E-isomers are produced. The authors demonstrate that, by utilizing a novel chelated ­ruthenium catalyst, selectivity for the Z-isomer can be achieved.
