New access to (η5-cyclohexadienyl)Mn(CO)3 and cationic (η6-arene)Mn(CO)3 complexes by Suzuki-Miyaura reactionCCDC reference numbers 782848 and 782849. For crystallographic data in CIF or other electronic format see DOI: 10.1039/c0dt01270j

First Suzuki-Miyaura coupling reactions applied to (η 5 -chloro-cyclohexadienyl)Mn(CO) 3 complexes are described and lead to the syntheses of (η 5 -aryl-cyclohexadienyl)Mn(CO) 3 and of cationic (η 6 -arene)Mn(CO) 3 complexes after rearomatization. The structures of two of the new complexes have been investigated by X-ray diffraction study. Suzuki-Miyaura coupling reactions of (η 5 -chloro-cyclohexadienyl)Mn(CO) 3 complexes lead to the syntheses of unprecedented (η 5 -aryl-cyclohexadienyl)Mn(CO) 3 and of cationic (η 6 -arene)Mn(CO) 3 complexes after rearomatization.
