“…Similar results were also observed when changing the solvent to THF or toluene. As an alternative synthetic method [29,30], the reaction of iPr Ar*SnMe 3 (7), obtained from conversions of iPr Ar*Li with Me 3 SnCl, with an excess of tin tetrachloride was investigated ( Figure 3). Yet, even after prolonged reaction times and high excess of SnCl 4 , only the dichloride iPr Ar*SnCl 2 Me (8) was isolated from these approaches.…”

In the last few decades, organotin hydrides have proven their potential as building blocks for a great variety of organometallic compounds. In this context, organotin hydrides with sterically shielding aryl substituents have attracted special interest, as these ligands can kinetically stabilize metastable products. The selective synthesis of aryltin halide compounds Ar*2SnCl2 and Ar*SnI3 featuring the highly sterically encumbered aryl ligand Ar* (iPrAr* = 2,6-(Ph2CH)2-4-iPrC6H2; MeAr* = 2,6-(Ph2CH)2-4-MeC6H2) is presented. These aryltin halides were converted into corresponding aryltin hydrides Ar*2SnH2 and Ar*SnH3, which exhibit a surprisingly high thermal stability and oxygen tolerance.

The controlled base hydrolysis of 2,6-Mes(2)C(6)H(3)SnCl(3) (1; Mes=mesityl) provided 2,6-Mes(2)C(6)H(3)Sn(OH)Cl(2).H(2)O (2) and the trinuclear organostannonic acid trans-[2,6-Mes(2)C(6)H(3)Sn(O)OH](3) (3), respectively. In moist C(6)D(6), 3 reversibly reacts with water to give the monomeric organostannonic acid 2,6-Mes(2)C(6)H(3)Sn(OH)(3) (3 a). The reaction of 3 with (tBu(2)SnO)(3), Ph(2)PO(2)H, and NaH, gives rise to the multinuclear hypercoordinated organostannoxane clusters [tBu(2)Sn(OH)OSnR(OH)(2)OC(OSntBu(2)OH)(2)(O)SnR(OH)(H(2)O)](2) (5), [RSn(OH)(2)(O(2)PPh(2))](2) (6), and Na(3)(RSn)(4)O(6)(OH)(3) (7), respectively (R=2,6-Mes(2)C(6)H(3)). The characterization of the new compounds is achieved by multinuclear NMR spectroscopy and electrospray mass spectrometry in solution and (119)Sn MAS NMR spectroscopy, IR spectroscopy, and X-ray crystallography in the solid-state.

Herein we report the syntheses of highly rigid silicon-and tincontaining cyclic and bicyclic compounds with unsaturated organic backbones. The syntheses proceed via di-lithiated diethynylbenzene derivatives. The protocols for the known precursor compounds were significantly improved in a two-step one-pot reaction with yields up to 45 % by alternating addition of the lithiation reagent and starting material. A total of ten compounds were synthesized and the molecular structure in the solid state was elucidated for six novel compounds. Hostguest-experiments with selected molecules were conducted to investigate on the potential of the complexation of small anions. All compounds were characterized by multinuclear NMR spectroscopy and elemental analyses or mass spectrometry and in most parts by SC-XRD analyses.
