Highly active metathesis catalysts selective for ROMP and RCM reactions |
摘要 |
The present invention relates to a kind of novel carbene ligands and ruthenium catalysts, which is highly active and selective for ROMP and RCM reactions, respectively. It discloses the significant electronic and steric 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 catalysts and the uses in metathesis. Moreover, the invention also provides effective methods of making various functional polymers by ROMP reaction in the presence of new ruthenium catalysts.
