Abstract
Chemically quite robust ruthenium carbene complexes 2-8 bearing one or two imidazolin-2-ylidene ligands are highly active catalysts for all types of r ing closing metathesis reactions (RCM). Importantly, they even allow the fo rmation of tetrasubstituted alkenes that were previously out of reach of ru thenium-based metathesis catalysts. (C) 1999 Elsevier Science Ltd. All righ ts reserved.
