For 10 points, name this metal located directly below boron on the Periodic Table, with atomic number 13 and symbol Al.
This element is complexed to two isobutyl groups, then dimerizes, to form a reducing agent that converts nitriles to aldehydes. Carboxylic acids can be reduced to primary alcohols using a much stronger reducing agent containing lithium, this element, and four hydrides. This element is produced at the cathode when its oxide is dissolved in cryolite and electrolyzed. In that oxide, this element has a +3 oxidation state and forms corundum. In the Bayer process, this element is extracted from bauxite, and it is then refined in the Hall-Heroult process.
