摘要：

[GRAPHICS] Trisubstituted alkenes have been prepared for the first time via intermolecular olefin cross metathesis, using 1,3-dimesityl -4,5-dihydroimidazol- 5-ylidene ruthenium alkylidene complexes 3a,b in good yields with moderate E selectivity. In addition, protected alcohols near the geminal disubstituted olefin improve reactivity for cross-metathesis.
