A Highly Efficient Ruthenium Catalyst for Metathesis Reactions

Abstract

A simple three-step synthesis leads to the formation of the active complex 1, which operates under very mild conditions (even at 0 °C!) and can be successfully applied in various types of olefin metathesis (ring-closing metathesis, cross metathesis, enyne metathesis), for example, in the cyclization of 2 to form 3.
