Two catalysts for the price of one : Air‐stable ruthenium complexes 1 and 2 (L=PCy, 1,3‐dimesityl‐4,5‐dihydroimidazol‐2‐ylidene) are catalyst precursors for the atom‐transfer radical polymerization of vinyl monomers. The catalytic activity is increased when the analogous cationic 14‐electron complexes are used. Unusually, these complexes also show a very high activity for the ring‐opening‐metathesis polymerization of low‐strain cyclic olefins.
