Description

Application

Umicore Precatalysts for Asymmetric and Cross-Coupling Catalysis

Catalyst for:

• Oxidative olefination reactions
• C-C bond cleavage of secondary alcohols
• Ortho C-H olefination of phenol derivatives
• Oxidative annulation of pyridines
• Oxidative ortho-acylation of benzamides with aldehydes via direct functionalization of the sp² C-H bond
• Amidation reactions
• Reductive alkylation reactions

Pentamethylcyclopentadienylrhodium(III) chloride dimer can be used as a catalyst for:

• The synthesis of multiaryl substituted naphthols via dual C-H bond functionalization of 2-aryloxypyridines.
• Regioselective C-N bond formation of azo compounds, wherein azide acts as a nitrogen source.
• Annulation of N-benzoylsulfonamide with isocyanide via C-H bond activation.
