Editing Tin(IV) chloride (section)

===Precursor to organotin compounds===
Anhydrous tin(IV) chloride is a major precursor in [[organotin chemistry]]. Upon treatment with [[Grignard reagent]]s, tin(IV) chloride gives tetraalkyltin compounds:<ref name = "Greenwood">{{Greenwood&Earnshaw}}</ref>
:SnCl<sub>4</sub> + 4 RMgCl → SnR<sub>4</sub> + 4 MgCl<sub>2</sub>
Anhydrous tin(IV) chloride reacts with tetraorganotin compounds in [[redistribution reaction]]s:
:SnCl<sub>4</sub> + SnR<sub>4</sub> → 2 SnCl<sub>2</sub>R<sub>2</sub>
These organotin halides are useful precursors to catalysts (e.g., [[dibutyltin dilaurate]]) and polymer stabilizers.<ref name=Ullmann>G. G. Graf "Tin, Tin Alloys, and Tin Compounds" in Ullmann's Encyclopedia of Industrial Chemistry, 2005 Wiley-VCH, Weinheim. {{doi|10.1002/14356007.a27_049}}</ref>
