2-Dicyclohexylphosphino-2',6'-dimethoxybiphenyl Usage And Synthesis
Uses    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.
Highly universal ligand for Suzuki-Miyaura coupling; aryl chlorides, hindered biaryls, heterobiaryls.
Reactions    
Ligand/palladium catalyst for general Suzuki-Miyaura cross-coupling reactions.
Ligand/palladium catalyst for the Suzuki-Miyaura coupling of aryltrifluoroborates with aryl chlorides.
Ligand/palladium catalyst for the Suzuki-Miyaura reaction of heteroaryl halides and heteroaryl boronic acids and esters.
Ligand/palladium catalyst for the Kumada-Corriu cross-coupling reaction.
Ligand/palladium catalyst for the borylation of aryl halides with pinacol borane.
Suzuki couplings involving amino acids. Synthesis of biaryl derivatives of 4-hydroxyphenyl glycine, tyrosine and tryptophan.
Synthesis of substituted adamantylzinc reagents using Mg-insertion in the presence of zinc chloride.
Highly efficient catalyst for the palladium-catalyzed Suzuki-Miyura reaction of heteroaryl halides and heteroaryl boronic acids
