A cross-metathesis reaction was achieved between acid- and base-sensitive functionalized olefins and electron-deficient olefins or allylsilane by using the recyclable ruthenium catalyst V at room temperature. The cross-metathesis products are isolated in moderate to good yield. Ratios of E and Z cross-metathesis products depend upon substituents on the electron-deficient coupling partner.
