An allyltrimethylated version of this element is used in a reaction which Furstner and Voightlander accelerated using halophilic activation. Its not copper or lithium, but after using a Gilman reagent, a reagent containing this as a central atom is added in the Saegusa-Ito oxidation, and it is used as an allyl donor in the Hosmi-Sakurai reaction. A pair of reactions that use this element immediately follow up its addition with catalytic titanium tetrachloride. A reagent containing one of these atoms bonded to 3 R groups and a chloride atom is used in the first step of a variant of the aldol condensation named for Mukaiyama, which generates an enol ether of this element. Its isotope 29 is use

Its isotope 29 is used for NMR. This element attaches to four methyl groups is the calibrating standards for proton NMR experiments, and like carbon this element has the ability to form long chains via catenation. For 10 points, name this element found in silanes and appears right below carbon on the periodic table.
