Difunctional derivatives of 1,5-pentanedithiol, 1,5-bis(trimethylstannylthio)pentane(CH2)5(SSnR 3)2 and 1,5-bis(3-trimethylstannylpropylthio)pentane (CH2)5[S(CH2)3SnR3] 2 (R = Me), differ by mutual arrangement of the tin and sulfur atoms and therefore react differently with N,4-dichlorobenzenesulfonamide sodium salt ArSO2N(Na)Cl (Ar = 4-ClC6H4). The first of these substrates possesses two direct Sn-S bonds which are cleaved by the action of 2 equiv of 4-ClC6H4SO2N(Na)Cl (desulfurization). The resulting pentamethylene-dithiobis-sulfonamide (CH2)5[SN(SnMe3)SO2Ar]2 undergoes oxidative imination of both S(II) atoms with additional 2 equiv of 4-ClC6H4SO2N(Na)Cl to afford sulfinimidamide derivative (CH2)5[S(=NSO2Ar)-N(SnR3)SO 2Ar]2. By contrast, both pairs of the sulfur and tin atoms in the bissulfide (CH2)5[S(CH2)3SnR3] 2 are separated by a trimethylene bridge, and this substrate reacts with 2 equiv of 4-ClC6H4SO2N(Na)Cl to form tin-containing bis-sulfimide (CH2)5[S(=NSO2Ar)(CH2) 3SnR3]2. According to the 1H and 13C NMR data, interaction between two pairs of the tin and sulfur atoms at both ends of the bis-sulfimide molecule gives rise to independent sterically favorable coordination rings.

Complexes of the general formula R3SnX, where X is the anion of benzoic acid, o-, m-, p-amino- or N-phenyl-o-amino-benzoic acid, have been prepared and characterised.A combination of molecular weight, infrared, 1H NMR and 119Sn Moessbauer measurements show that, the amino-nitrogen atoms are not coordinated to tin.When R= phenyl or cyclohexyl, the compounds are monomeric and four-coordinate, and when R is alkyl (Me, n-Pr, n-Bu) they are monomeric and five-coordinate, with a bidentate carboxylate in the equatorial position of a trigonal bipyramidal structure.

Negatively substituted halomethanes were allylated easily by allyltin compounds via radical chain reaction involving S//H prime process. Aryl, aralkyl, and alkyl halides underwent similar chain reactions only when the tin compound was charged in excessive amounts.

The mechanism for the process giving trimethyl(benzoyloxy)stannane by the reaction of benzoyl peroxide with trimethylphenylstannane or tetramethylstannane has been investigated.The kinetic results exclude the possibility that the decomposition of the pero
