Ruthenium metathesis catalyst and method for producing olefin reaction product by metathesis reaction using the same

Abstract

The invention has an object of safely and simply preparing a large amount of a ruthenium metathesis catalyst, which is used as a catalyst for a carbon-carbon bond formation using, particularly, a metathesis reaction. The metathesis catalyst has the following complex composition (A) or (B). The composition (A) includes RuX,(arene)(PR,R,R,) and R,CHX,, R,C ≡CH or R,CHX,and a reducing agent, wherein X,and X,respectively are a halogen atom; arene is a hydrocarbon having a benzene ring; R,, R,and R,, which may be the same or different, respectively are an alkyl group having 1-8 carbon atoms, a cycloalkyl group having 3-8 carbon atoms or an optionally substituted aryl group, wherein the substituent group is an alkyl group having 1-8 carbon atoms, an alkoxy group having 1-8 carbon atoms, an alkylamino group having 1-8 carbon atoms or a halogen atom; R,is an alkyl group which has 1-8 carbon atoms and may have an ether bond or an ester bond, an optionally subsituted aryl group, wherein the substituent group is a halogen atom or a hydroxyl group; or cycloalkyl group having 3-8 carbon atoms; and R,is an optionally substituted alkyl group which has 1-8 carbon atoms and may have an ether bond or an ester bond, wherein the substituent group is a halogen atom or a hydroxyl group, an aryl group or a cycloalkyl group having 3-8 carbon atoms. The composition B includes [RuX,(arene)],, PR,R,R,, R,C≡CH or R,CHX,and a reducing agent, wherein X,, arene, R,, R,, R,, R,and R,are the same as defined above.
