专利号:US-6794534-B2 优先权日:2000-06-23 标题:Synthesis of functionalized and unfunctionalized olefins via cross and ring-closing metathesis 发明人:GRUBBS ROBERT H; CHATTERJEE ARNAB K; MORGAN JOHN P; SCHOLL MATTHIAS; CHOI TAE-LIM 权利人:CALIFORNIA INST OF TECHN 摘要:The invention is directed to the cross-metathesis and ring-closing metathesis reactions between geminal disubstituted olefins and terminal olefins, wherein the reaction employs a Ruthenium or Osmium metal carbene complex. Specifically, the invention relates to the synthesis of α-functionalized or unfunctionalized olefins via intermolecular cross-metathesis and intramolecular ring-closing metathesis using a ruthenium alkylidene complex. The catalysts preferably used in the invention are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are each independently an anionic ligand; n L is a neutral electron donor ligand; and, n R, R 1 R 6 , R 7 , R 8 , and R 9 are each independently hydrogen or a substituent selected from the group consisting of C 1 -C 20 alkyl, C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl.
