资源简介：
A rhodium(II) dibenzotetramethylaza[14]annulene
dimer ([(tmtaa)Rh]2) undergoes metathesis reactions with
[CpCr(CO)3]2, [CpMo(CO)3]2, [CpFe(CO)2]2, [Co(CO)4]2, and [Mn(CO)5]2 to form (tmtaa)Rh-M complexes
(M = CrCp(CO)3, MoCp(CO)3, FeCp(CO)2, Co(CO)4, or Mn(CO)5). Molecular structures
were determined for
(tmtaa)Rh-FeCp(CO)2, (tmtaa)Rh-Co(μ-CO)(CO)3, and (tmtaa)Rh-Mn(CO)5 by X-ray diffraction. Equilibrium
constants measured for the metathesis reactions permit the estimation
of several (tmtaa)Rh-M bond dissociation enthalpies (RhCr
= 19 kcal mol–1, RhMo = 25 kcal mol–1, and RhFe = 27 kcal mol–1). Reactivities of the bimetallic complexes with synthesis gas to
form (tmtaa)Rh-C(O)H and M-H are surveyed.
