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.

, p. 1451 - 1457 (2002)
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.
Direct Detection, Dimerization, and Chemical Trapping of Dimethyl- and Diphenylstannylene from Photolysis of Stannacyclopent-3-enes in Solution

Dimethyl- and diphenylstannylene (SnMe2 and SnPh2, respectively) have been successfully detected and characterized in solution. The stannylenes were generated by photolysis of 1,1,3-trimethyl-4-phenyl- (2) and 3,4-dimethyl-1,1-diphenylstannacyclopent-3-ene (3), respectively, which have been shown to extrude the species cleanly and in high (0.6 2SnCl2) as the stannylene substrate. Laser flash photolysis of 2 and 3 in deoxygenated hexanes affords promptly formed transient absorptions assigned to SnMe2 (λmax = 500 nm; ε500 = 1800 ± 600 M-1 cm-1) and SnPh2 (λmax = 290, 505 nm; ε500 = 2500 ± 600 M-1 cm-1), respectively, which decay with absolute second-order rate constants within a factor of 2 of the diffusional limit in both cases. The decay of the stannylenes is accompanied by the growth of new transient absorptions ascribable to the corresponding dimers, the structures of which are assigned with the aid of DFT and time-dependent (TD) DFT calculations at the (TD)ωB97XD/6-31+G(d,p)C,H,O-LANL2DZdpSn level of theory. Dimerization of SnMe2 affords a species exhibiting λmax = 465 nm, which is assigned to the expected Sn=Sn doubly bonded dimer, tetramethyldistannene (Me2Sn=SnMe2, 16a), in agreement with earlier work. In contrast, the spectrum of the dimer formed from SnPh2 exhibits strong absorptions in the 280-380 nm range and a very weak absorption at 650 nm, on the basis of which it is assigned to phenyl(triphenylstannyl)stannylene (17b). The calculations suggest that 17b is formed via ultrafast rearrangement of a novel phenyl-bridged stannylidenestannylene intermediate (20), which can be formed either directly by "endo" dimerization of SnPh2 or by isomerization of the "exo" dimer, tetraphenyldistannene (16b); the predicted barriers for these rearrangements are consistent with the experimental finding that the observed product is formed at close to the diffusion-controlled rate. Absolute rate and equilibrium constants are reported for the reactions of SnMe2 and SnPh2 with Me2SnCl2 and methanol (MeOH), respectively, in hexanes at 25 °C.

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.
Synthesis and characterization of some organotin(IV) adducts containing a related series of pyridines: Crystal structure of [SnMe2Cl2(bu2bpy)]

Organotin(IV) complexes of [SnR(4-n)Cln] (n = 2, R = Me, nBu; n = 1, R = Ph) react with the bidentate pyridyl ligand 4,4′-di-tert-butyl-2,2′-bipyridine (bu2bpy) to give hexa-coordinated adducts with the general formula [SnR(4-n)Cln(bu2b py)]. However, the reaction of these organotin(IV) complexes with the corresponding monodentate ligand 4-tert-butylpyridine (bupy) resulted in the formation of the hexa-coordinated complex [SnMe2Cl2(bupy)2] and the penta-coordinated complexes [SnR(4-n)Cln(bupy)] (n = 2, R = nBu; n = 1, R = Ph). Moreover, the reaction of the above organotin(IV) complexes with 4,4′-trimethylenedipyridine (tmdp) yields hexa-coordinated adducts with the general formula [SnR2Cl2(tmdp)] (R = Me, nBu) and the penta-coordinated complex [ClPh3Sn-μ-(tmdp)SnPh3Cl] in the solid state. The resulting complexes have been characterized by multinuclear NMR (1H, 13C, 119Sn) spectroscopy and elemental analysis. NMR data shows that the triphenyltin(IV) adducts are not stable in solution and dissociate to give tetra-coordinated tin(IV) complexes. The X-ray crystal structure determination of [SnMe2Cl2(bu2bpy)] reveals that the tin atom is hexa-coordinated in an octahedral geometry with a trans-[SnMe2] configuration.

The presence of a reactive B-Cl bond allowed for the direct functionalization of the boron center in antiaromatic chloroborole ClBC 4Ph4, thus allowing for a selective fine tuning of the optical properties of borole derivatives and facilitating a potential new approach toward the introduction of borole moieties into the backbone of organic π-conjugated frameworks.
