It is bonded to lithium in a Gilman reagent, and its high ductility and conductivity make it popular for electrical wiring.
This element complexes with TMEDA in a modification of the Cadiot-Chodkiewicz coupling. The iron-metabolizing hephaestin protein is dependent on this element, while its deficiency causes sparse, coarse hairs to form in Menkes disease. This element is found at the center of a cytochrome c complex and replaces a diazonium salt on a benzene ring in the (*) Sandmeyer reaction. Reducing this element's sulfate to its oxide can be used to detect reducing sugars in Benedict's test. Kayser-Fleischer rings form around the iris when this element builds up in the liver in Wilson's disease. A classic semiconductor contains yttrium, barium, and the oxide of this element. It is bonded to lithium in a Gilman reagent, and its high ductility and conductivity make it popular for electrical wiring. For 10 points, name this metal whose alloy with tin is called bronze.
