설명

애플리케이션

Hindered Phosphine salt employed with a Pd(0)-15-membered, triolefinic, macrocyle in Suzuki cross-coupling reactions of aryl bromides and chlorides. Also used in Heck coupling of non-activated vinyl tosylates with electron deficient olefins.

Ligand used in the Pd-catalyzed enantioselective α−arylation of N-boc-pyrrolidine.
