Abstract

Ruthenium complexes include those represented by Formula 1. A new process for producing the ruthenium complexes represented by the Formula 1. The ruthenium complexes represented by the Formula 1 are useful as precatalysts and/or catalysts in olefin metathesis reactions such as ring-closing metathesis, homometathesis, cross-metathesis, ethenolysis, isomerization reaction, diastereoselective ring-rearrangement metathesis, 'alkene-alkyne' type metathesis, ring-opening metathesis polymerization, and metathetic depolymerization.
