Abstract
The stable chlorostannylene(II) LSnCl 1 reacted with bases or salts (KOH, t-BuOK, Ph3CSLi or Li2S), respectively, which led to the formation of a variety three-coordinated tin(II) chalcogens (O or S) (compounds 2–5). Compounds 2 and 5 are bridged bimetallic organotins(II) supported by a bidentate β-diketiminato ligand. Furthermore, the catalytic activity of compounds 2–5 for hydroboration with benzaldehyde and acetophenone were investigated, respectively. In the X-ray analyses of all stannylene chalcogenide compounds, the pyramidalization on the tin center are useful to enhanced p-character of lone pair. All compounds were characterized by 1H NMR and 13C NMR spectroscopy, single crystal X-ray structural analysis and elemental analysis.
