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 C4 -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 Cn, H2n, Y or Cn, F2n Y radial 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 C4 aryl; R3, R4, R5, R6, R7, R8, R9, R10, R11 are, separately, a hydrogen, C1-C6 alkyl, a C1-C6 perhalogenoalkyo, or a C5 or C6 aryl; wherein R9, R10,R11 can be a heterocycle; X is an anion, R1 and R2 can form, with the N and the C to which they are attached, a heterocycle.
