The cross coupling reaction of ( p ‐chloroanisole)tricarbonylchromium complex ( 1 ) with thiophene derivatives under palladium‐catalyzed conditions leads to the selective formation of tricarbonyl‐η 6 ‐[(2‐thiophenyl)arene]‐ or ‐η 6 ‐[(2‐thiophenyl)carbonylarene]chromium complexes ( 2 or 3 ) depending on reaction conditions. The conformation of complexes 2 and 3 in the solid state as well as in solution are reported.
