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. … Meer weergeven 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 … Meer weergeven Organotin compounds can be synthesised by numerous methods. Classic is the reaction of a Grignard reagent with tin halides for example tin tetrachloride.

WebOrganotins are widespread contaminants especially of water environments. Their chemically versatile structure makes organotin compounds able to bind to a variety of biomolecules thus widely affecting biological functions. Trisubstituted molecules, namely tributyltin (TBT) and triphenyltin (TPhT), have been widely employed in antifouling paints and are also … WebOrganotin compounds have a backbone of the tetravalent tin IV molecule. When fully alkylated, that is for tetrabutyltin and tributyltin oxide (TBT-O-TBT), TBT acts like a typical organic compound and is easy to extract into solvent. However, as the molecule becomes jedan dl koliko ima ml
