Pump, Eva; Poater, Albert; Zirngast, Michaela; Torvisco, Ana; Fischer, Roland; Cavallo, Luigi; Slugovc, Christian published the artcile< Impact of Electronic Modification of the Chelating Benzylidene Ligand in cis-Dichloro-Configured Second-Generation Olefin Metathesis Catalysts on Their Activity>, SDS of cas: 16426-64-5, the main research area is benzylidene ruthenium imidazolidene carbene chelating complex preparation catalyst polymerization; impact electronic modification chelating benzylidene ruthenium dichloro metathesis catalyst; configured olefin metathesis catalyst benzylidene ruthenium imidazolidene carbene complex; cis trans isomerization benzylidene ruthenium imidazolidene carbene dichloro complex; crystal mol structure benzylidene ruthenium imidazolidene carbene chelating complex.
A series of electronically modified second-generation cis-dichloro ruthenium ester chelating benzylidene complexes was prepared, characterized, and benchmarked in a typical ring-opening metathesis polymerization (ROMP) experiment The electronic tuning of the parent chelating benzylidene ligand (2-Et ester benzylidene) was achieved by substitution at the 4- and 5-positions with electron-withdrawing nitro or electron-donating methoxy groups. The effect of the electronic tuning on the cis-trans isomerization process was studied exptl. and theor. D. functional theory calculations clearly revealed the influence of electronic modification on the relative stability between the cis and trans isomers, which is decisive for the activity of the studied compounds as initiators in ROMP.
