The present invention relates to a kind of novel carbene ligands and corresponding new ruthenium catalysts, which are highly active and selective for ROMP and RCM reactions. It discloses the significant electronic effect of different substituted carbene ligands on the catalytic activity and stability of corresponding carbene ruthenium complexes; some of novel ruthenium complexes in the invention can be broadly used as catalysts highly effectively and selective for ROMP and RCM reactions. The invention also relates to preparation of new ruthenium complexes and the use in metathesis. Moreover, the invention also provides efficient methods of making various functional polymers and quality-modified nitrile butadiene rubbers by different metathesis and hydrogenation reactions in the presence of the new ruthenium catalysts.
