Abstract
A ruthenium-containing metathesis catalyst system which contains a ruthenium compound (A), a phosphorus, arsenic, or antimony compound (B), and a compound (C) containing at least one carbon-to-carbon triple bond. The mole ratio of compounds A:B:C is typically in the range of about 1.0:0.01-100:0.01-500. The ruthenium compound (A) is a Ru(II), Ru(III), or Ru(IV) compound containing an anionic ligand (X) and optionally an arene ligand and optionally a phosphorus, arsenic, or antimony compound ligand. The compound (B) is optional if the ruthenium compound (A) contains a phosphorus-, arsenic-, or antimony-containing ligand. Hydrogen gas is used as an activator. A process for metathesis of olefins involves reacting at least one olefin with the catalyst system described herein.
