  Linkage Isomerization Reactions of M(CO)₂L Complexes (M = (η⁵-C₅H₅)Mn, (η⁵-C₅H₅)Re, or (η⁶-C₆H₆)Cr; L = 2,3-Dihydrofuran): A Step-Scan FTIR and DFT Study

  摘要：

  The linkage isomers, M(CO)(2)-(eta(1)-(O)-2,3 DHF) and M(CO)(2)-(eta(2)-(C,C)-2,3 DHF) [M = (eta(5)-C5H5)Mn, (eta(5)-C5H5)Re, (eta(6)-C6H6)Cr; DHF = dihydrofuran] are formed upon photolysis of the parent M(CO)(3) complexes in the presence of 2,3-DHF. The rearrangement of the oxygen bound to the thermodynamically favored a bound complex is followed on the millisecond to microsecond time scale using step-scan FTIR. The rate of the isomerization reaction increases in the order Re < Mn < Cr primarily due to a decrease in the activation enthalpy. The experimental data along with theoretical calculations suggest that the rearrangement proceeds intramolecularly in which the metal migrates from one functional group to another.
