Organotin chemistry is the scientific study of the synthesis and properties of organotin compounds or stannanes, which are organometallic compounds containing tin carbon bonds. The first organotin compound was diethyltin diiodide ((CH3CH2)2SnI2), discovered by Edward Frankland in 1849. … Zobacz więcej 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 … Zobacz więcej Organotin compounds can be synthesised by numerous methods. Classic is the reaction of a Grignard reagent with tin halides for example tin tetrachloride. An example is … Zobacz więcej An organotin compound is commercially applied as stabilizers in polyvinyl chloride. In this capacity, they suppress degradation by removing allylic chloride groups and by absorbing Zobacz więcej • Organostannane addition • Tributyltin azide • Carbastannatranes Zobacz więcej Important reactions, discussed above, usually focus on organotin halides and pseudohalides with nucleophiles. In the area of organic synthesis, the Stille reaction is considered … Zobacz więcej The toxicities of tributyltin and triphenyltin derivatives compounds are comparable to that of hydrogen cyanide. Furthermore, tri-n-alkyltins are phytotoxic and therefore cannot be … Zobacz więcej • National Pollutant Inventory Fact Sheet for organotins • Industry information site • Organotin chemistry in synthesis Zobacz więcej WitrynaThe analysis of organotin compounds is becoming increasingly important in both environmental analysis and in food and consumer product analysis.

10.8: Reactions of Alkyl Halides - Grignard Reagents
WitrynaIn order to prepare Grignard reagents with the aforementioned catalysts, it has been necessary to employ finely divided magnesium particles, e.g. 200 mesh or finer. On the other hand, magnesium turnings have been found to be highly useful in the present process for making organotin compounds. Witryna12 lip 2002 · The determination of organotin compounds in water using gas chromatography-tandem mass spectrometry (GC-MS-MS) is described.
