RUTHENIUM-BASED CATALYTIC COMPLEXES AND THE USE OF SUCH COMPLEXES FOR OLEFIN METATHESIS

摘要

The invention relates to all compounds of the formula (I) or (II) in which: L is a neutral ligand; X, X' are anionic ligands; R¹ and R² are, separately, a hydrogen, a C₁-C₆ alkyl, a C₁-C₆ perhalogenoalkyl, a aldehyde, a ketone, an ester, a nitrile, an aryl, a pyridinium alkyl, an optionally substituted C₅ or C₆ pyridinium alkyl, perhalogenoalkyl or cyclohexyl, a C_nH2_nY or C_nF_2nY radical 10 with n between 1 and 6 and y an ionic marker, or a radical having the formula: wherein R¹ can be a radical of formula (Ibis) when the compound has formula (I) or of formula (IIbis) when the compound has formula (II), R³ is a C₁-C₆ alkyl, or a C₅ or C₆ cycloalkyl or a C₅ or C₆ aryl; R⁰, R⁴, R⁵, R⁶, R⁷, R⁸, R⁹, R¹⁰, R¹¹ are, separately, a hydrogen, C₁-C₆alkyl, a C₁-C6 perhalogenoalkyl, or a C₅ or C6 aryl; wherein R⁹, R¹⁰, R¹¹ can be a heterocycle; X¹ is an anion. R¹ and R² can form, with the N and the C to which they are attached, a heterocycle.
