The ambiphilic N-heterocyclic carbene ligand, indol-2-ylidene (IdY, <b>A</b>), is described. A series of indolenium precursors (<b>2a</b>-<b>f</b>) were prepared on a gram scale in good yields. Trapping experiments with elemental selenium, [RhCl(cod)]<sub>2</sub> and CuCl lead to IdY-supported materials, respectively. Computational and spectroscopic studies revealed the ambiphilicity of IdY. The copper complexes (<b>6</b>) show high percent buried volume (%V<sub>bur</sub> = 58.1) and allow for carboboration of terminal alkynes within 30 minutes as synthetically useful yields and high regioselectivity.

Substituted γ-benzyl-L-glutamates and β-benzyl-L-aspartates have been obtained from the alkali metal salts of the corresponding amino acid copper complexes and substituted benzyl halides under various experimental conditions. The use of a sequestering agent to remove the copper from the intermediate ester complexes allows the introduction of relatively sensitive ester groups. Several other types of ester were also prepared in the same way.
