  Bonding modes of arenes in photogenerated (arene)Cr(CO)5 complexes

  摘要：

  Detailed kinetics studies of arene displacement by 1-hexene from the ten (arene)Cr(CO)(5) complexes (arene = C6H6-n(CH3)(n); n = 2-5) generated by pulsed laser flash photolysis have been conducted. The data indicate that all reactions obey a 'reversible dissociation-competition for the [Cr(CO)(5)] intermediate' mechanism. The systematic variations in rate constants for unimolecular dissociation of arenes in the presence of l-hexene 'trap' strongly support 'edge-on' bonding of the arene to Cr for the methyl-substituted benzene compounds in which there is a C-C 'ring-edge' unsubstituted by methyls. Where no such ring-edge is present, i.e., for mesitylene, 1,2,3,5-tetramethylbenzene, 1,2,4,5-tetramethylbenzene and pentamethylbenzene, the kinetics data suggest that a rapid equilibrium is established between two binding modes, the second possibly through the ring center.
