Modular Diamino- and Dioxophosphine Oxides and Chlorides as Ligands for
C—C and C—N Coupling with Aryl Chlorides. —
35- 107 Transition-Metal-Catalyzed
The use of air-stable diaminophosphine oxide (Ia) as ligand in palladium-catalyzed
Suzuki-type reactions of aryl chlorides is reported. In addition, the unprecedented
application of diaminophosphine chloride (Ib) to palladium-catalyzed amination reactions of aryl chlorides and bromides, and palladium- and nickel-catalyzed C—C coupling reactions is presented. Catalyst system Pd(dba)2/(Ic) is found to exhibit catalytic
activity comparable to that observed with Pd(dba)2/(Ib) in the amination reaction of
chloride (IIe). — (ACKERMANN*, L.; BORN, R.; Angew. Chem., Int. Ed. 44 (2005)
