General description

The ChemBeads product of the 1,1′-Bis(diphenylphosphino)ferrocene (DPPF) ligand. DPPF is a bis-phosphine ligand bearing two diphenylphosphine moieties with a ferrocene backbone. Loaded on glass beads for use in high-throughput expermentation (HTE).

Application

  • DPPF has been used as a ligand in:
  • The ruthenium catalyzed N-alkylation of amines and sulfonamides using borrowing hydrogen methodology.[1] (19191700)
  • The cooperative Cu/Pd catalyzed borylallenylation of trifluoromethyl-1,3-enynes to generate conjugated bisallenes.[2] (36321461)
  • The cooperative Cu/Pd catlyzed borocarbonylation of ethylene.[3] (36226440)
  • The gold catalyzed synthesis of 2-phosphoryl indolin-3-ones.[4] (35815915)
  • The iron-catalyzed vinylzincation of terminal alkynes.[5] (34935372) ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
  • For general uses, product is also available in powdered form (177261)

A cooperative Cu/Pd-catalysed borylallenylation of 2-trifluoromethyl-1,3-enynes with propargylic carbonates under mild reaction conditions was developed. This method provides facile and efficient access to conjugated bisallenes with a broad range of functional groups. Both aromatic and aliphatic 1,3-enynes can be utilized
