Opis

Opis ogólny

SPhos [2-Dicyclohexylphosphino-2′,6′-dimethoxybiphenyl] is an air-stable, electron-rich biaryl phosphine ligand developed by the Buchwald group to enhance the reactivity of palladium catalysis during cross-coupling reactions.

Zastosowanie

SPhos may be used as a ligand in the following processes:

• Palladium catalyzed Suzuki-Miyaura cross-coupling reaction between Boc-protected aminomethyltrifluoroborate and aryl chlorides or hetaryl chlorides to form the corresponding aminomethylarenes.
• Palladium catalyzed Suzuki-Miyaura cross-coupling reaction between 4-methyl-substituted piperidinylzinc reagent and different aryl or heteroaryl iodides to form various substituted piperidines.
• Intramolecular Suzuki-Miyaura coupling to form the 18-membered macrocyclic ring during the multi-step synthesis of riccardin C.

Utilized in conjunction with palladium to form a highly active catalyst for C-N bond formation.
Highly universal ligand for Suzuki-Miyaura coupling; aryl chlorides, hindered biaryls, heterobiaryls.

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.
