MULTICOORDINATED METAL COMPLEXES FOR USE IN METATHESIS REACTIONS

摘要

Improved catalysts useful in alkyne or olefin metathesis are made by bringin g into contact a multi-coordinated metal complex comprising a multidentate Schiff base ligand, and one or more other ligands, with a selected activatin g compound under conditions such that at least partial cleavage of a bond between the metal and the multidentate Schiff base ligand of said metal complex occurs.
