Highly active phosphine-free carbene ruthenium catalyst for cross-metathesis of acrylonitrile with functionalized olefins

The carbene ruthenium complex [1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene](C 5H 5N) 2(Cl) 2Ru CHPh ( 8 ) was prepared by the reaction of [1,3-bis (2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene](PPh 3)(Cl) 2Ru CHPh ( 7 ) with pyridine and used as a highly effective catalyst for the...
