Gabriel LemcoffUV irradiation of latent sulfur-chelated ruthenium olefin metathesis precatalysts produced a cis-dichloro−trans-dichloro photoisomerization. The enhanced activity of the trans isomer, when aromatic substituents were attached to the sulfur chelating atom, induced several metathesis reactions, including ROMP, at room temperature.
