Abstract
The invention relates to new (pre)catalysts of ruthenium complexes of formula 1, wherein L1, X, X′, R1, R2, R3 and n are defined herein. The novel ruthenium complexes of formula 1 are convenient (pre)catalysts for metathesis reactions and can be applied, e.g., for ring-closing metathesis, cross metathesis or ene-ine metathesis reactions. Another aspect of the invention are the novel intermediates of formula 2.
