For small scale and high throughput uses, product is also available as ChemBeads (932191)

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.
