Abstract

Abstract Efficient and recyclable ruthenium catalysts were synthesized from readily available polystyrene-or silica-supported phosphine ligands. Catalysts bound to the polymer support through an ether linkage showed good to excellent activity towards the N-alkylation of primary and secondary amines to afford the alkylated products in 62–99% yield at 120–140 C. The supported phosphine ligand/ruthenium ratio was found to be crucial for higher ...
