Abstract
The grafting of the preformed Pc-L* (pyridine containing macrocyclic ligands) copper(i) complexes on different ordered and non-ordered silicas, and their use, under heterogeneous batch conditions, as catalysts for the olefin cyclopropanation are reported. High yields (up to 99%) and good recyclability in halogen-free solvent reactions were obtained, together with negligible copper leaching (0.1% of total copper). © The Royal Society of Chemistry 2013.
