methanol at room temperature produces stable (N^C)-cyclometallated ruthenium(II) complexesvia C–H bond activation/deprotonation. This method can be applied also to nitrogen-containing molecules: N-phenylpyrazole, 2-phenyl-2-oxazoline and benzo[h]quinoline. N-Phenyl-pyrazole, [RuCl2(p-cymene)]2 and diphenylacetylene directly lead to alkyneinsertion into the metallacycle C–Ru bond.
