Liquid phase hydrogenation of olefins using heterogenized ruthenium complexes as high active and reusable catalyst

The homogeneous ruthenium complexes were immobilized onto tannin grafted micelle templated silica (MTS–BT) to prepare heterogeneous MTS–BT–Ru catalysts. The catalyst was found to be highly active in liquid phase hydrogenation of olefins. The heterogenized Ru complexes also exhibited excellent stability, reusability and catalytic efficiency. Furthermore, this methodology could extend to heterogenize other complexes to improve their reusability and stability.
