Abstract

Treatment of tetrakis(trimethylstannyl)methane with one equivalent of methyllithium followed by one equivalent of Me₃MCl gives mixtures of the type C(SnMe₃)_n(MMe₃)_4-n (M = Si, Pb; n = 0−3), which have been characterised by multinuclear (¹³C, ²⁹Si, ¹¹⁹Sn, ²⁰⁷Pb) NMR. The main component (ca. 40%) is in each case (Me₃Sn)₃ CMMe₃, but considerable amounts of the other tetrametallamethanes are also present.

Inorganic lead compounds as stabilizers for polymers or as components in glasses, the toxicity of lead chemicals, and basic research in organolead chemistry are important topics of discussion. In lead chemistry, nuclear magnetic resonance (NMR) spectroscopy has become one of the prominent tools for studying lead compounds in solution, and it may also be valuable for studying various classes of solid lead compounds. This chapter aims to present the results of the study of ²⁰⁷Pb NMR measurements performed in liquids. In addition, the chapter outlines some aspects of the solid-state ²⁰⁷Pb NMR, as it is a rapidly growing area at present. Multinuclear magnetic resonance (mNMR) is used for obtaining consistent information on the systems under consideration. A larger set of ²⁰⁷Pb NMR data helps in understanding the NMR parameters of the lighter magnetically active isotopes in Group IV of the periodic table, in particular for ^l19Sn and ²⁹Si nuclei. Furthermore, ²⁰⁷Pb NMR parameters serve as a crucial test for the validity of theoretical models, aiming at the description of chemical and physical properties of the heavy elements. Many old problems in the solid-state chemistry of lead can be tackled, taking advantage of the improvements in modern NMR instrumentation.
Silylmethyl and silylamino groups as ligands in tin(II), tin(IV), lead(II) and lead(IV) compounds-a multinuclear magnetic resonance study
1990, Spectrochimica Acta Part A: Molecular Spectroscopy
We have studied tin(II), tin(IV), lead(II) and lead(IV) compounds of the type M[CH(SiMe₃)₂]₂ (5), M[N(SiMe₃)₂]₂ (6), M[N(SiMe₃)SiMe₂^tBu]₂ (7), Me₃MCH₂SiMe₃ (1), Me₃MCH(SiMe₃)₂ (3), Me₃MNHSiMe₂^tBu (2), Me₃MN(SiMe₃)₂ (4), Me₂M[N(SiMe₃)₂]₂, (8) and (Me₃M)₂NSiMe₂^tBu (9) by ¹³C, ¹⁵N, ²⁹Si, ¹¹⁹Sn and ²⁰⁷Pb NMR spectroscopy. In some cases, two-dimensional (2-D) ¹³C/¹H and ²⁹Si/¹H heteroscalar-correlated NMR spectra served for the comparison of the signs of the respective coupling constants [ⁿJ(M ¹³C), ²J(M²⁹Si) and ⁿJ(M¹H)]. The ¹³C and ¹⁵N NMR parameter of comparable compounds (replacement of the CH or CH₂ fragment by a nitrogen atom or the NH group, respectively), show analogous trends. In the monomeric M(II) compounds (5, 6, 7) the peculiar electronic situation at the metal is reflected by the extreme deshielding of the metal nuclei (e.g. δ²⁰⁷ Pb for 5b = +9110 ppm), by the strongly deshielded ¹³C (5) and ¹⁵N nuclei (6, 7), as well as by large negative contributions to the reduced nuclear spin—spin coupling constants ¹K(M¹³C) (5) and ¹K(M¹⁵N) (6). In the M(II) compounds 5 the ¹¹⁹Sn and, in particular, the ²⁰⁷Pb longitudinal and transverse nuclear relaxation is dominated by the chemical-shift-anisotropy mechanism. This is also true for 6 and 7, in which the transverse relaxation rate is further increased by scalar relaxation of the second kind owing to partially relaxed scalar coupling ¹J(M¹⁴N).
