HIGHLY ACTIVE METATHESIS CATALYSTS SELECTIVE FOR ROMP AND RCM REACTIONS Russian patent published in 2015 - IPC B01J31/22 C07F15/00 C08F4/80 

FIELD: chemistry.

SUBSTANCE: invention relates to a ligand of metal complex. A ligand of metal complex having the following structure or wherein Z is CH₂=; m=0 or 1, n=0 or 1; when m=0, X is HN, C₁-C₂₀-alkylimino or C₆-C₂₀-arylamino; when m=1, X is CH₂; X is HN or C₁-C₂₀-alkylimino; $$$$ is a single bond; when n=1, X¹ is CH₂ or carbonyl; Y¹ is oxygen or carbonyl; R¹ is hydrogen; R² is C₁-C₂₀-alkyl or C₆-C₂₀-aryl; E is hydrogen, halogen, nitro, C₁-C₄-alkoxy, C₁-C₄-alkoxycarbonyl or C₁-C₈-alkylaminosulfonyl; E¹ and E² are each independently selected from the group consisting of H and halogen; E³ is hydrogen; E⁴ is hydrogen or C₁-C₄-alkyl; E⁵ and E⁶ are either hydrogen or halogen, C₁-C₄-alkyl or C₁-C₆-alkoxy; E⁷ is hydrogen or C₁-C₄-alkyl. A transition metal complex, a method of carrying out a metathesis reaction with olefin substrate, use of a transition metal complex for rubber depolymerisation and rubber hydrogenation.

EFFECT: transition metal complexes offering high activity and selectivity for ROMP and RCM reactions.
