The bigger the better: The new well-defined [Pd(IPr*)(cin)Cl] pre-catalyst is described (see scheme). This complex proves to be highly active in the Suzuki-Miyaura cross-coupling for the synthesis of tetra-ortho- substituted biaryls under mild conditions.

(Figure Presented) Biaryl monophosphorus ligands containing a 2,3-dihydrobenzo[d][1,3]oxaphosphole framework are highly effective for the palladium-catalyzed Suzuki-Miyaura cross-coupling reactions of a wide range of substrates. Ligand 1 has demonstrated excellent performance for coupling reactions of extremely hindered arylboronic acids.

(Chemical Equation Presented) Cool couplings: Complex, hindered biaryls have been prepared at temperatures ranging from 0°C to room temperature, or with gentle heating. The Pd-PEPPSI-IPent catalyst (see scheme) nicely couples starting materials containing acidic moieties and routinely prepares biaryl derivatives where one or both rings comprising the biaryl are heterocyclic. Ar1=hindered aryl or heteroaryl, Ar2=unactivated aryl or heteroaryl.
