Ruthenium–indenylidene complexes in ring opening metathesis polymerization (ROMP) reactions

The ring opening metathesis polymerization (ROMP) of cycloocta-1,5-diene (COD) is mediated by a series of six well-defined ruthenium-based indenylidene catalysts. The polymerization kinetics are monitored and compared with three generations of Grubbs’ catalyst. Moderate control over the polymerizations was observed for both benzylidene and indenylidene-based catalysts.

A series of well-defined ruthenium-based indenylidene catalysts are tested in ring opening polymerization metathesis (ROMP) with cycloocta-1,5-diene. The reactivity of the catalysts is examined by the polymerization kinetics.Figure optionsDownload as PowerPoint slide
