Solid-phase olefin cross-metathesis promoted by a linker.

Olefin cross-metathesis couples two alkenes to form complex molecules and has been widely used in solution-phase organic synthesis. However, this powerful method has rarely been used in solid-phase organic synthesis. Herein we report that olefin cross-metathesis is a synthetically viable method particularly when a traceless longer linker is inserted between solid support and reacting olefins.
