We describe the development of (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2, a versatile precatalyst scaffold for Pd-catalyzed cross-coupling. Our new system is more active than commercially available (eta3-cinnamyl)2(mu-Cl)2Pd2 and is compatible with a range of NHC and phosphine ligands. Precatalysts of the type (eta3-1-tBu-indenyl)Pd(Cl)(L) can either be isolated through the reaction of (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 with the appropriate ligand or generated in situ, which offers advantages for ligand screening. We show that the (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 scaffold generates highly active systems for a number of challenging cross-coupling reactions. The reason for the improved catalytic activity of systems generated from the (eta3-1-tBu-indenyl)2(mu-Cl)2Pd2 scaffold compared to (eta3-cinnamyl)2(mu-Cl)2Pd2 is that inactive PdI dimers are not formed during catalysis.
