Dinuclear Group IV Metal Complexes based on a Bis(indenyl)-(E/Z)-Stilbene Platform: A Potential Prototype of “Photoswitchable” Catalysts for Olefin Polymerization

The preparation of dizirconium complexes based on a novel bis(indenyl)-(E/Z)-stilbene platform was explored. Negishi coupling between the in situ-generated diorganozincates obtained from the respective o/m/p-(E/Z)-dibromostilbenes and the bromo-functionalized zirconocene (η5-Cp*)(η5-2-methyl-4-bromoindenyl)ZrCl2,...
