Scheme 2. Scope of the Direct Arylation of Anisole–Cr(CO)₃ Complexes 1a–t with 2a.

Reactions carried out on a 0.5 mmol scale with respect to the limiting reagent. Yields are of isolated product. ^b Performed with p-NMe₂–C₆H₄–CO₂H. ^c o,p-Bisarylated product 3ba′′ (3%) was also obtained. ^d o,p-Bisarylated product 3ca′′ (4%) was also obtained. ^e o,p-Bisarylated product 3da′′ (7%) was also obtained. ^f o,p-Bisarylated product 3ra′′ (3%) was also obtained. ^g Performed without TMP.
