Molecular Dynamics within Diorganotin Systems: Solution and Solid State Studies of New Mixed Distannoxane Dimers [tBu2(Cl)SnOSn(Cl)R2]2

Di-tert-butyltin oxide, (tBu2SnO)3, reacts with R2SnCl2 to give mixed distannoxanes [tBu2(Cl)SnOSn(Cl)R2]2 (1, R = Me; 2, R = Et; 3, R = iPr; 4, nBu) whereas di-tert-butyltin hydroxide chloride, [tBu2Sn(OH)Cl]2, reacts with [nBu2SnO]n to give the chlorohydroxydistannoxane [tBu2(OH)SnOSn(Cl)nBu2]2, 5; the dimeric nature of these tetraorganodistannoxanes was confirmed by crystal structure determinations of 1 and 4. Although stable in the solid state, compounds 1-4 rearrange to give a number of distannoxanes in solution. Addition of R2SnCl2 (R = Me, iPr, nBu) to solutions of 1, 3, and 4, respectively, causes displacement of tBu2SnCl2 with concomitant formation of [(tBu2SnCl2)(R2SnO) 2(R2SnCl2)] and [(R2SnCl2)(R2SnO)2(R 2SnCl2)]. Thus 1-4 can be regarded as (R2SnO)2 units which are stabilized by two tBu2SnCl2 molecules. NMR data indicate that reaction between (1Bu2SnO)3 and tBu2SnCl2 gives rise to an equilibrium involving linear [tBu2Sn(Cl)OSn(Cl)tBu2] and the novel three-quarter ladder compound [tBu2SnCl2][tBu2SnO] 2. Formation of trinuclear tin species is also evident from electrospray mass spectrometric studies.

HYDROXID-HALOGENID-VERBINDUNGEN DES DI-t-BUTYL-SUBSTITUIERTEN ZINNS

The di-t-butyltin hydroxide halides t-Bu2Sn(OH)X (X = F, Cl or Br) have been prepared starting from the dihalides t-Bu2SnX2 or the oxide (t-Bu2SnO)3.X-Ray analysis of the three compounds show dimeric molecules: two 5-coordinated tin atoms and the oxygen atoms of the hydroxyl groups are linked to a four-membered ring.As confirmed by the IR spectra, the molecules in the crystal are held together by O-H...X hydrogen bonds.These are strong in the hydroxide fluoride but are weak in the analogous chloride and bromide.

Reaction between tBuMgCl and SnCl4, illustrating the solvent-dependent predominant formation of Cl(tBu2Sn) nCl (THF, n = 1; Toluene, n = 2; Hexane, n = 3) and the subsequent wavelength-selective photochemical transformation of n = 3 → 2 → 1

The addition of THF solutions of tBuMgCl to SnCl4 in varying solvents (S) results in a dramatic change of the predominant product obtained Cl(tBu2Sn)nCl (n = 1-3). For S = THF the product obtained was tBu2SnCl2, S = toluene, benzene yields Cl(tBu2Sn)2Cl, while for S = hexane the tristannane Cl(tBu2Sn)3Cl was isolated in 45% yield. The last compound is photochemically sensitive when irradiated at 350 nm to form Cl(tBu2Sn)2Cl. Irradiation of this latter material with a 254 nm lamp results in the formation of tBu2SnCl2.

The first spacer-bridged tetraorganodistannoxanes with a mixed double ladder structure

The reaction of Me3SiCH2Cl2 Sn(CH2)3SnCl2Ph (6) with (tBu2SnO)3 gave a statistical mixture of the corresponding tetraorganodistannoxanes whereas the reaction of the spacer-bridged ditin tetrachlorides RCl2Sn(CH2)4SnCl2R (3, R = Me3CCH2; 4, R = Me2CHCH2; 10, R = Me3SiCH2) with the polymeric spacer-bridged ditin oxides [R(O)Sn(CH2)4-Sn(O)R]n (7, R = Me2CHCH2; 8, R = Me3CCH2; 11, R = Me3SiCH2) provided the mixed double ladder compounds {[R(Cl)Sn(CH2)4 Sn(Cl)R][R′(Cl)Sn(CH2)4Sn(Cl)R′] O2}2 (9, R = Me3CCH2, R′ = Me2CHCH2; 12, R = Me3CCH2, R′ = Me3SiCH2) in almost quantitative yield. In solution, 9 and 12 are in equilibrium with their corresponding dimers, as was evidenced by 119Sn NMR spectroscopy, molecular mass determination, and electrospray mass spectrometry. The molecular structures of 9 and 12 were established by single crystal X-ray diffraction.
