Ruthenium-based catalytic complexes and the use of such complexes for olefin metathesis

摘要

Ruthenium complex (I), are new. Ruthenium complex of formula (I) are new. L : imidazolidine compound of formula (a) or 2,3-dihydro-1H-imidazole of formula (b); R : alkyl or aryl; either R 1>alkyl, perfluoroalkyl, aryl or ruthenium complex of formula (c); and R 2>alkyl, perfluoroalkyl or aryl; or R 1>, R 2>form a cycle. An independent claim is included for a molecule constituted by (I) substituted by an ionic unit. [Image] [Image].
