Synthesis and catalytic olefin metathesis activity of amberlyst-15 supported cyclic and bicyclic alkyl amino carbene ruthenium complexes

Abstract Amberlyst-15 supported cyclic alkyl amino carbene and bicyclic ruthenium olefin metathesis catalysts for sustainable catalytic applications have been synthesized by the well-known wet impregnation method utilizing ionic complex/support interaction. Surface coverages are as high 4 7 wt% were achieved in case of significantly higher pore volume Amberlyst-15, compared to Amberlyst-36. These phase separable show activity cross metathesis, ring closing ethenolysis reactions reported heterogenized catalysts. Leeching tests revealed no more than 1.5 ppm content investigated reactions, which is well below accepted 10 limit consumer products.
