Document Type and Number:
WIPO Patent Application WO2000043343
Kind Code:
A3
Abstract:
A method for the cross-metathesis of terminal olefins is disclosed. The method describes making disubstituted internal olefin products by contacting a first terminal olefin with another first terminal olefin to form a dimer and then contacting the dimer with a second terminal olefin in the presence of a catalyst having formula (I), where M may be Os or Ru, R and R<1> may be the same or different and may be hydrogen or a substitutent group selected from C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, aryl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkenyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkylsulfonyl, and C1-C20 alkylsulfinyl. X and X<1> may be the same or different and may be any anionic ligand. L and L<1> may be the same or different and may be any neutral electron donor.
