This paper describes the synthesis and characterization
of trimethylaluminum (<b>2a</b>), dimethylaluminum (<b>3a</b>), and triphenylboron complexes (<b>7</b>) supported by functional
amine-linked NHC ligands. The chemical reactivity studies with carbodiimide
and isocyanate were preformed with <b>2a</b> and <b>3a</b>, 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.
