✦ Synopsis

1999 structure structure (organic substances) K 9000 06 -015 A Novel Class of Ruthenium Catalysts for Olefin Metathesis. -Title compounds (I) and (II) are readily prepared by reacting Ph-CH=RuCl 2 (PPh 3 ) 2 or Ph-CH=RuCl 2 (PCy 3 ) 2 with 2.2 equivalents of the appropriate imidazolin-2-ylidene. They constitute a new class of rutheniumbased metathesis catalysts containing alkylidene groups and N-heterocyclic carbenes as ligands. The value of these compounds is briefly demonstrated in ring-opening metathesis polymerization and ring-closing metathesis reactions. The simple access to chiral catalysts (II) appears promising for enantioselective metathesis reactions. -(WESKAMP, T.; SCHATTENMANN, W. C.;

The different nature of carbene ligands is clearly demonstrated by the first ruthenium-based complexes 1, which contain both alkylidene and N-heterocyclic carbene moieties. The latter exhibit a pronounced Lewis base behavior. Moreover, this difference forms the basis of the high catalytic activities
