Transmetallation with (*) palladium by an organometallic of this element allows cross-coupling with an alkyl halide in the Stille reaction.
The tetrachloride of this element is used to toughen glass by depositing an oxide film, and its dichloride forms an unusual corner-shared layer structure due to the inert pair effect, which also allows dialkyls of this element to form metal-metal double bonds. In the presence of a radical initator, the (**) tributyl hydride of this element generates alkyl radicals and is used as a dehalogenating agent. Transmetallation with (*) palladium by an organometallic of this element allows cross-coupling with an alkyl halide in the Stille reaction. Cornish pasties were eaten by miners of this element, deposits of which made Britain important to ancient trading routes. For 10 points, name this Group 14 metal which is alloyed with copper to make bronze.
