Abstract
The invention relates to compositions of hexacoordinated ruthenium and osmium carbenes with a carbonyl group as ligand and a vinyl group as substituent on the carbene group as catalysts for the photoinduced ring-opening metathesis of strained cycloolefins. It also relates to novel hexacoordinated ruthenium and osmium carbenes having a carbonyl group as ligand and a vinyl group as substituent on the carbene group, to compositions of the catalyst with cycloolefins, and to the polymerization process.
