Descripción

Application

DavePhos may be used as a ligand in the following reactions:

• Palladium catalyzed sp³ arylation of 2-substituted-N-iminopyridinium ylides with different aryl chlorides to yield functionalized pyridines.
• Preparation of functionalized benzylic sulfones via palladium-catalyzed Negishi cross-coupling between alkyl sulfones and aryl halides.
• C-C Coupling of 3-haloquinolines with aryl sulfinates via palladium-catalyzed desulfitative arylation to form the corresponding biaryl compounds.

Ligand used in a Pd-catalyzed Suzuki aryl-aryl coupling leading to benzodioxepines.
