<p>The invention relates to new (pre)catalysts of ruthenium complexes of formula 1, <CHEM> wherein L<1>, X, X', R<1>, R<2>, R<3>, Z and n are as defined in claim 1. 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 is the novel intermediates of formula 2. <CHEM></p> |
