설명

애플리케이션

1,2-Bis(dicyclohexylphosphino)ethane can be used as a ligand for:

• Pd-catalyzed decarbonylative C-H coupling of azoles and aromatic esters.
• Ni-catalyzed cross-coupling reaction of aryl fluorides and primary amines.

Reactant involved in:

• Investigations of the role of ligand-based steric effects during the polymerization
• Synthesis of molybdenum nitrosyl complexes for use as Imine hydrogenation catalysts
• Irreversible thermal linkage isomerization of switchable C-N-bound isomers
• Chelating for conversion of trans complexes to cis complexes

Precursor for Iridium trisboryl complexes and the substituent effect on borylation reactions

Ligand for palladium(II) complex catalyzed hydrogenation reactions
