| Popis: | A series of NNN-pincer iron complexes bearing ketimine-type iminobipyridene (BPI) ligands were prepared. These iron complexes were effective catalysts for the hydrosilylation of olefins using primary, secondary, and tertiary silanes. The effect of the substituents on the imino carbon on the catalytic activity was examined, and it was found that the appropriate combination of the imino carbon and imino nitrogen substituents led to complexes with quite high catalytic activity: the turnover number achieved was up to 42000. These iron catalytic systems provide a low-cost and promising alternative to currently employed precious metal systems for the hydrosilylation of olefins. |
