Beschreibung

Anwendung

AlPhos is a biaryl monophosphine ligand that can be used:

• In the Pd-catalyzed Buchwald-Hartwig cross-coupling reactions.
• To synthesize highly regioselective aryl fluorides by Pd-catalyzed fluorination of a variety of activated aryl and heteroaryl triflates and bromides.
• To prepare aryl thioethers by C–S cross-coupling of thiols with aromatic electrophile in the presence of palladium catalyst.
