• Synthesis and characterization of alkyl group-tagged ruthenium indenylidene complexes.
• Olefin metathesis activities of the alkyl group-tagged ruthenium indenylidene complexes.
• Comparison with the commercial available phenyl ruthenium indenylidene complex is made.
• The changes in the geometry from the phenyl group by the alkyl groups showed a negligible effect on the catalytic activity.
We report on the synthesis of ruthenium indenylidene catalysts [RuCl2(3-R-1-indenylidene)(PCy3)2 in which R is iso-propyl (7a), tert-butyl (7b) or cyclohexyl (7c)]. The obtained alkyl tagged indenylidene catalysts were analyzed by means of IR, elemental analysis, NMR and single crystal X-Ray diffraction analysis. Furthermore, the catalytic performance of these new complexes was examined in different metathesis reactions: ring-closing metathesis (RCM), ring-closing ene-yne metathesis (RCEYM), ring-opening metathesis polymerization (ROMP) and cross metathesis (CM), exhibiting a comparable activity in comparison with the commercially available catalyst 3a.
The synthesis and characterization of three first-generation alkyl group tagged ruthenium indenylidene catalysts are reported, as well as their catalytic performance in olefin metathesis reactions.Figure optionsDownload as PowerPoint slide
