(Tetramethylcyclobutadiene)cobalt complexes 10. Synthesis of arene complexes [(C4Me4)Co(arene)]+ and mechanism of the arene exchange reaction

The cluster anion [Co 3 (CO) 3 (μ 2 -CO) 3 (μ 3 -C 8 H 8 )] -(2) reacts with fragments [(ring)M] + and [(cod)M] + to give the Co 3 M clusters (ring)MCo 3 (CO) 3 (μ 3 -CO) 3 (μ 3 -C 8 H 8 ) {(ring)M = CpFe (3a), Cp*Fe (3b), CpRu (4a), (C 4 Me 4 )Co (5)} and (cod)MCo 3 (CO) 3 (μ 3 -CO) 3 (μ 3 -C 8 H 8 ) {M = Rh (6), Ir (7)}, respectively.

The indenyl‐benzene complex [(η5‐indenyl)Fe(η‐C6H6)]+ (2) was synthesized by photochemical reaction of the cyclohexadienyl derivative [(η5‐C6H7)Fe(η‐C6H6)]+ and indenyl anion with the subsequent treatment of complex (η5‐C6H7)Fe(η5‐indenyl) formed by acetic acid. Visible light irradiation of cations [(η5‐indenyl)Fe(η6‐indene)]+ (1) or 2 in the presence of substituted benzenes in CH2Cl2 results in arene exchange giving [(η5‐indenyl)Fe(η6‐arene)]+ (arene=o‐xylene (3 a), mesitylene (3 b), hexamethylbenzene (3 c) and [2.2]paracyclophane (3 d)). The rate of this reaction is lower than for the related cyclopentadienyl complex [CpFe(η‐C6H6)]+. μ‐Pentaphospholyl triple‐decker complex [(η5‐indenyl)Fe(μ‐η:η‐cyclo‐P5)FeCp*]+ (4) was synthesized by photochemical reaction of 1 with Cp*Fe(η‐cyclo‐P5). The structures of 2PF6, 3 cPF6 and 4PF6 were determined by X‐ray diffraction. According to energy decomposition analysis, the metal‐benzene bonding in 2 is weaker than in [CpFe(η‐C6H6)]+ but stronger than in [Cp*Fe(η‐C6H6)]+. The mechanism of thermal benzene replacement in 2 and [CpFe(η‐C6H6)]+ as well as structure of excited state were analyzed by DFT calculations.
