Title:
クロスメタセシスおよび閉環メタセシスによる、官能性および非官能性オレフィンの合成
Document Type and Number:
Japanese Patent JP2004510699
Kind Code:
A
Abstract:
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 alpha-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 formulawherein:M is ruthenium or osmium;X and X<1 >are each independently an anionic ligand;L is a neutral electron donor ligand; and,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 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.
