Two p ‐cymene‐ruthenium complexes 1 and 2 were isolated in high yields by treating the [RuCl 2 ( p ‐cymene)] 2 dimer with new hybrid phosphane‐ or NHC‐linked diene ligands. Both complexes were fully characterized by NMR spectroscopy, and the molecular structure of the ruthenium– p ‐cymene complex 1 , containing the phosphane–diene ligand system, was determined by X‐ray diffraction analysis. The catalytic activities of both compounds were probed in atom‐transfer radical addition (ATRA) and polymerization (ATRP), in the cyclopropanation of olefins, in the ring‐opening metathesis polymerization (ROMP) of norbornene, and in the synthesis of enol esters from hex‐1‐yne and 4‐acetoxybenzoic acid.
