Chemistry of Some Organotin Compounds
Organotin compounds (OTCs) are characterized as having at minimum one covalent bond between carbon and tin atoms, and are usually denoted by the formula RnSnX4-n (n = 1-3, R = aryl or alkyl, X = halogen ion or a carboxylate, etc.). There are several methods to synthesis organotin compounds, they are Grignard and Kocheshkov reactions, Wurtz reaction and alkylation method. The tin has two stable state, (II) and (IV). Sn (II) forms pyramidal sp3 complexes as well as trigonal bipyramidal sp3d complexes, whereas Sn (IV) forms trigonal bipyramidal sp3d complexes or octahedral sp3d2 complexes.
