<p>The invention relates to new (pre)catalysts of ruthenium complexes of formula (I), 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 i.e. for ring-closing metathesis, cross metathesis or ene-ine metathesis reactions. Another aspect of the invention are the novel intermediates of formula (II).</p> |
