WitrynaC. Esser, in Comprehensive Medicinal Chemistry II, 2007 5.09.4.2.2.2 Organotin compounds. Organotin compounds are chemicals with at least one covalent Sn–C bond. They are widely used as polyvinyl chloride (PVC) stabilizers, biocides, or antifouling paints and have given rise to ubiquitous environmental contamination. 87 … 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 … Zobacz więcej • Organostannane addition • Tributyltin azide • Carbastannatranes Zobacz więcej Important reactions, discussed above, usually focus on organotin halides and pseudohalides with nucleophiles.
