Application

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

This manuscript details the development of the nickel-catalyzed arylation of oxazoles and benzoxazoles with aryl halides. A series of aryl, heteroaryl, and druglike electrophiles relevant to pharmaceutical applications were surveyed. The desired arylated products were obtained in synthetically useful yields
