Popis: Six olefin metathesis catalysts, based on a common ruthenium precursor featuring a hydroxy-substituted N-heterocyclic carbene ligand, were successfully prepared and fully characterised. As proof-of-concept, two of them ([Ru]isonico and [Ru]dmab) were directly immobilised on a solid support. These non-covalently heterogenised catalysts are efficient in different metathesis reactions and sufficiently stable to be used for repeated runs under batch and continuous flow conditions. In nonpolar media such as n-hexane, the catalytic character of the metathesis reactions is truly heterogeneous, and the contamination of the products with ruthenium is very low. © 2021 The Authors.
