Subtle Reactivities of Boron and Aluminum Complexes with Amino-Linked N-Heterocyclic Carbene Ligation Chia-Cheng Tai Ya-Ting Chang Jie-Hong Tsai Titel Jurca Glenn P. A. Yap Tiow-Gan Ong 10.1021/om200878e.s001 https://acs.figshare.com/articles/dataset/Subtle_Reactivities_of_Boron_and_Aluminum_Complexes_with_Amino_Linked_N_Heterocyclic_Carbene_Ligation/2557234 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. 2012-01-23 00:00:00 carbodiimide characterization LigationThi preformed Suzuki ligand NHC triphenylboron reagent temperature conditions method complex Carbene synthesis Aluminum Complexes covalency Subtle Reactivities chemical reactivity trimethylaluminum Boron isocyanate interaction substrate chemical reactivity studies noninnocent nature bond dimethylaluminum
