  Subtle Reactivities of Boron and Aluminum Complexes with Amino-Linked N-Heterocyclic Carbene Ligation

  摘要：

  This paper describes the synthesis and characterization of trimethylaluminum (2a), dimethylaluminum (3a), and triphenylboron complexes (7) supported by functional amine-linked NHC ligands. The chemical reactivity studies with carbodiimide and isocyanate were preformed with 2a and 3a, illustrating the noninnocent nature in Al-carbene bonding. However, the boron-carbene interaction is quite robust against addition of these substrates even at higher temperature conditions. The subtle difference in chemical reactivity between aluminum and boron is attributed from the metal-carbene bond covalency. Development of the catalytic method for Suzuki-Miyaura coupling utilizing triphenylboron reagent supported by amino-NHC is also presented.
