DETAILS

Description (English)
Application
Bulky biarylphosphine ligand utilized in the palladium catalyzed Stille cross-coupling reaction.8
Bulky phosphine ligand used in a Pd-catalyzed 2,3-diarylation of α,α-disubstituted-3-thiophenemethanols via cleavage of C-H and C-C bonds.
Ligand utilized in amination of aryl halides and aryl triflates.1Catalyst for:
• Decarboxylative cross-coupling of dialkoxybenzoic acids with diaryl disulfides or diaryl diselenides2
• Stereoselective preparation of imidazolidinones via intramolecular hydroamination of N-allylic-N-arylureas3
• Regioselective arylation of olefins with aryl chlorides4
• Cross-coupling reaction for the synthesis of polyunsaturated macrolactones5
• Regioselective O-alkylation reactions6
• Sonogashira-type cross coupling7
Packaging
1, 5, 25, 100 g in glass bottle
