Chemistry of Some Organotin Compounds

Abstract

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.
