THE ULTRAVIOLET DEGRADATION OF THE METHYLTIN CHLORIDES IN CARBON TETRACHLORIDE AND WATER
Blunden, Stephen J.
, p. 149 - 160 (1983)
The ultraviolet degradation of the methyltin chlorides in carbon tetrachloride and water has been quantitatively studied by 1H NMR spectroscopy.In the organic solvent trimethyltin chloride degraded to an inorganic tin species, via di- and mono-methyltin intermediates; in water, a monomethyltin derivative was not observed.The ultraviolet breakdown of dimethyltin dichloride and monomethyltin trichloride in these solvents was also studied, and the approximate relative rates of degradation were established.

The possibility of forming extended structures by self-association using transition metal halides as donors to organotin acceptors has been investigated. The stannylplatinum(IV) complex [PtClMe2(SnMe2Cl)(bu2bpy)] forms a 1:1 adduct [PtClMe2(SnMe2Cl)(bu2bpy)]·Me 2SnCl2 with Me2SnCl2 in which the organoplatinum complex acts as a donor to the organotin halide. Similarly, [PtClMe2(SnMeCl2)(bu2bpy)] forms adducts [PtClMe2(SnMeCl2)(bu2bpy)]·MeSnCl 3 or [PtClMe2(SnMeCl2)(bu2bpy)]·Me 2SnCl2, and [{PtClMe2(bu2bpy)}2(μ-SnCl2)] forms [{PtClMe2(bu2bpy)}2(μ-SnCl2)] ·Me2SnCl2. Structure determinations on selected compounds show that the donor is the Pt-Cl group and the acceptor tin centre is 5-coordinate. In the similar bromo complex [PtBrMe2(SnMeBr2)(bu2bpy)]·Me 2SnBr2 both the Pt-Br and PtSn-Br groups coordinate to the Me2SnBr2 acceptor with short (3.14 or 3.29 A) and long (3.99 or 4.05 A) contacts, respectively, so that the acceptor tin centre adopts distorted octahedral stereochemistry in the solid state and a folded polymeric structure is formed. Reaction of [{PtClMe2(bu2bpy)}2(μ-SnCl2)] with AgO3SCF3 yields the complex [{PtClMe2(bu2bpy)}(μ-SnCl2){PtMe 2(bu2bpy)O3SCF3}], which is fluxional in solution.
COMPORTEMENT DE LA LIAISON Co-C DANS UNE SERIE DE COMPLEXES MODELES ALKYLES DU COBALT: MeCo(Chel)*B EN PRESENCE DE MeSnCl3 OU DE Me2SnCl2
Darbieu, M.H.,Cros, G.
, p. 327 - 340 (1983)
The behaviour of systems involving tin derivatives MeSnCl3 or Me2SnCl2 with a series of model vitamin B12 complexes MeCo(Chel)*B (with Chel=DMG, BAE, BAE(CF3), BAE(CF3)2, Salen, AESalen, AEHap, (Do)(Doh), TIM) was investigated through 1H and 13C NMR, EPR, VPC, and polarographic measurements.Consideration of the reduction potentials E1/2(CoIII -> CoII) shows that the behaviour of the Co-C bond (cleavage, dinuclear adduct formation (Co, Sn), no reaction) is mainly influenced by the electron donor ability of the equatorial ligand and by the nature of the tin centre.
A utility for organoleads: Selective alkyl and aryl group transfer to tin
Arias-Ugarte, Renzo N.,Pannell, Keith H.
, p. 1703 - 1708 (2018/02/09)
Me4Pb and Ph4Pb readily transfer methyl or phenyl groups to an equivalent molar ratio of tin(iv) chlorides in the order SnCl4 > MeSnCl3 > Me2SnCl2 > Me3SnCl, often in a selective manner. Me3PbCl and Ph3PbCl specifically transfer a single methyl/phenyl group under the same reaction conditions to produce recovered yields in >75%. Specific transfer of 2 methyl groups from PbMe4 can be achieved at elevated temperatures and/or a 2:1 molar ratio Pb:Sn.
Salicylaldehyde-(2-hydroxyethyl)imine - A flexible ligand for group 13 and 14 elements

The reaction of salicylaldehyde-(2-hydroxyethyl)imine (H2L), 1, with organoelement halides from group 13 and 14 leads to a variety of coordination compounds. Depending on the size of the central atom and the organic substituents, tetra-, penta- or hexacoordinated complexes emerge. When the central atom of the complex has a small atom radius and small substituents, like methyl groups, coordination number four is preferred. Thereby macrocyclic compounds of the composition L2(SiMeR)2 (R = Me, cyclohexyl) are formed. With phenyl substituted element halides Ph2ECl2 pentacoordinated complexes LEPh2 (E = Si, Ge, Sn) were isolated. Hexacoordinated complexes of the composition L2E (E = Si, Sn) were obtained from ECl4 and 1. A surprising result was obtained from the reaction of 1 with InCl3. The resulting complex is a monoanionic trimer, obeying the composition [HNEt3][L3In3Cl3(μ3-OH)].(DME)2(THF) in the solid state structure. The prepared compounds were characterised by NMR and IR spectroscopy, elemental and X-ray structure analysis. Furthermore solid state NMR measurements and chemical shift tensor analysis with the help of quantum chemical methods were used to analyse the electron density distribution around the central atoms of several products. The results of this study demonstrate the structural variety that can be created with a single O,N,O' chelating ligand.
