Abstract

Desulfurization or thermal decomposition of overcrowded 1,2,3,4,5-tetrathiagermolane 2 resulted in the formation of novel folded dithiadigermetane 3 via stereospecific [2+2]cycloaddition of intermediary germanethione 1 bearing two different bulky substituents.

Tb=2,4,6-tris[bis(trimethylsilyl)methylphenyl Mes=mesityl X-Ray structure analysis of $2$ is also described.

An extremely hindered digermene (E)-Tbt(Mes)GeGe(Mes)Tbt (1; Tbt=2,4,6-tris[bis(trimethylsilyl)methyl]phenyl; Mes=mesityl) was synthesized. X-ray crystallographic analysis of the hexane solvated single crystal [1·0.5hexane] revealed that 1 has an extremely long germanium–germanium double bond [2.416(2) Å] as that of a carbon-substituted digermene. The temperature-dependent change of UV–Vis absorption of digermene 1 in solution indicated the quantitative interconversion between 1 and the corresponding germylene Tbt(Mes)Ge: (3). The thermodynamic parameters (ΔH=14.7±0.2 kcal mol⁻¹ and ΔS=42.4±0.8 cal mol⁻¹ deg⁻¹) for the dissociation of digermene 1 to germylene 3 were obtained from temperature dependence of the absorption of 1. Since the reactivity of germylene 3 is much higher than that of digermene 1, almost all the intermolecular reactions of 1 in solution proceeded via dissociated 3. For instance, the reaction of 1 with oxygen in solution resulted in a non-stereospecific formation of the cis- and trans-1,3,2,4-dioxadigermetanes 11 and 7 via the initial formation of germanone 12 derived from oxygenation of the dissociated germylene 3. In case of the oxidation in the solid state, however, digermene 1 reacted with O₂ without dissociation to give the corresponding trans-substituted 1,3,2,4-dioxadigermetane stereospecifically. The reaction of digermene 1 with W(CO)₅(THF) was also examined to give the corresponding terminal tungsten complex of the dissociated germylene 3, i.e. Tbt(Mes)GeW(CO)₅ (23), as a marginally stable orange yellow paste.
Recent advances in the chemistry of group 14-group 16 double bond compounds
2001, Advances in Organometallic Chemistry
This chapter discusses the remarkable progress in the chemistry of heavy ketones leading to the systematic comparison of their structures and properties that are capable of existence as stable species if their highly reactive M=X bond is adequately protected toward dimerization. Kinetic stabilization is superior to thermodynamic stabilization to elucidate the intrinsic nature of heavy ketones. A more general account of the whole chemistry of stable double bonds between heavier Group 14 and Group 16 elements is reviewed. The structural features of their M=X bonds (M = Si, Ge, Sn; X = chalcogen atom), such as trigonal planar geometry and bond shortening compared to the corresponding M–X single bonds are similar to those of ketones, heavy ketones have much higher reactivity because of their weak π bonds. The systematic study on heavy ketones containing silicon through lead using steric protection with the Tbt group reveals that a heavy ketone containing lead, R₂Pb═X, is unique in that it is less stable than its isomeric lumbylene RPb–XR.
