Abstract
The synthesis and characterization of two ruthenium complexes bearing chelating carbene ligands is described. Carbene precursors, 2-(2-vinylphenyl)pyridine and 10-vinylbenzo[h]quinoline, are applied to prepare (SPY-5-31)-dichloro-(κ2(C,N)-N-2-(2-vinylbenzylidene)pyridine(1,3-bis(2,4,6-trimethylphenyl)4,5-dihydroimidazol-2-ylidene)ruthenium (VIII) and (SPY-5-31)-dichloro-(κ2(C,N)-2-(benzo[h]quinolin-10-yl)methylidene)(1,3-bis(2,4,6-trimethylphenyl)4,5-dihydroimidazol-2-ylidene)ruthenium (IX). Both catalysts/initiators are used to perform ring-closing metathesis (RCM) and ring-opening metathesis polymerizations (ROMP). RCM experiments reveal significant thermal stability of the catalysts under forcing reaction conditions such as boiling toluene for 48 h. Even challenging substrates such as diethylallyl(2-methylallyl)malonate are completely transformed with low catalyst loadings (0.1 mol % at 110 °C). The high thermal stability, i.e., latency, might be explained by a slow generation of the catalytically acti...
