Chelated ruthenium catalysts can facilitate highly chemoselective olefin metathesis. Terminal and internal Z olefins reacted selectively to form new Z olefins in the presence of internal E olefins. Chemoselectivity for terminal olefins was also observed over both sterically hindered and electronically deactivated alkenes.
螯合钌催化剂可以促进高度化学选择性的烯烃复分解。在内E烯烃存在下,末端Z烯烃和内Z烯烃选择性地反应形成新的Z烯烃。还观察到末端烯烃相对于空间位阻和电子失活的烯烃的化学选择性。
