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.

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
用于 Suzuki-Miyaura 偶联反应的高通用配体；芳基氯、位阻二芳基、杂二芳基化合物。
