SYNTHESIS OF FUNCTIONALIZED AND UNFUNCTIONALIZED OLEFINS VIA CROSS AND RING-CLOSING METATHESIS

摘要

PROBLEM TO BE SOLVED: To provide a method for the synthesis of functionalized and unfunctionalized olefins via 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.

SOLUTION: The catalysts preferably used are of the general formula wherein: M is ruthenium or osmium; X and X1 are each independently an anionic ligand; L is a neutral electron donor ligand; and R, R1, R6, R7, R8, and R9 are each independently hydrogen or a substituent selected from the group consisting of C1-C20 alkyl, etc.
