Complementary palladium-catalyzed methods for directarylation of oxazole with high regioselectivity (>100:1) at both C-5 and C-2 have been developed for a wide range of aryl and heteroaryl bromides, chlorides, iodides, and triflates. C-5 arylation is preferred in polar solvents with phosphines 5 or 6, whereas C-2 arylation is preferred by nonpolar solvents and phosphine 3. This represents the first
Room-Temperature Gold-Catalysed Arylation of Heteroarenes: Complementarity to Palladium Catalysis

Tailoring of the pre‐catalyst, the oxidant and the arylsilane enables the first room‐temperature, gold‐catalysed, innate C−H arylation of heteroarenes. Regioselectivity is consistently high and, in some cases, distinct from that reported with palladium catalysis. Tolerance to halides and boronic esters, in both the heteroarene and silane partners, provides orthogonality to Suzuki–Miyaura coupling.
