Organotin
Organotin compounds or stannanes are chemical compounds based on tin with hydrocarbon substituents. Organotin chemistry is part of the wider field of organometallic chemistry. The first organotin compound was diethyltin diiodide (), discovered by Edward Frankland in 1849. The area grew rapidly in the 1900s, especially after the discovery of the Grignard reagents, which are useful for producing Sn–C bonds. The area remains rich with many applications in industry and continuing activity in the research laboratory. Structure Organotin compounds are generally classified according to their oxidation states. Tin(IV) compounds are much more common and more useful. Organic derivatives of tin(IV) The tetraorgano derivatives are invariably tetrahedral. Compounds of the type SnRR'R''R have been resolved into individual enantiomers. Organotin halides Organotin chlorides have the formula for values of ''n'' up to 3. Bromides, iodides, and fluorides are also known but less important. The ...

Trimethyltin Chloride
Trimethyltin chloride is an organotin compound with the formula . It is a white solid that is highly toxic and malodorous. It is susceptible to hydrolysis. Synthesis Trimethyltin chloride can be prepared by the Redistribution (chemistry), redistribution reaction of tetramethyltin with tin tetrachloride. : This is the Kocheshkov redistribution reaction. It is performed under an inert atmosphere, such as argon, typically with no solvent. A second route to involves treating the corresponding Organotin chemistry#Organotin oxides and hydroxides, hydroxide or oxide with a halogenating agent such as hydrogen chloride or thionyl chloride (): : Uses Trimethyltin chloride is used as a source of the trimethylstannyl group. For example, it is a precursor to vinyltrimethylstannane and indenyltrimethylstanane: :CH2=CHMgBr + Me3SnCl → Me3SnCH=CH2 + MgBrCl :LiC9H7 + Me3SnCl → Me3SnC9H7 + LiCl An example of an Organolithium reagent, organolithium reagent reacting with Me3SnCl to form a tin- ...
