| Resumo |
The reaction of diorganotin sulfides, <i>cyclo</i>-(R<sub>2</sub>SnS)<i><sub>n</sub></i> (R=Me, <i>n</i>-Bu; <i>n</i>=3; R=<i>t</i>-Bu; <i>n</i>=2) with the corresponding diorganotin dichlorides, R<sub>2</sub>SnCl<sub>2</sub>, provided the tetraorganodistannathianes, (R<sub>2</sub>ClSn)<sub>2</sub>S (<b>1</b>, R=Me; <b>2</b>, R=<i>n</i>-Bu; <b>3</b>, R=<i>t</i>-Bu). <sup>1</sup>H-, <sup>13</sup>C-, and <sup>119</sup>Sn-NMR studies indicate that these compounds are kinetically labile and in equilibrium with the starting materials. Addition of equimolar amounts of [(Ph<sub>3</sub>P)<sub>2</sub>N]Cl to the reaction mixtures gave the chloride complexes [(Ph<sub>3</sub>P)<sub>2</sub>N]<sup>+</sup>[S(SnR<sub>2</sub>Cl)<sub>2</sub>Cl]<sup>−</sup> (<b>4</b>, R=Me; <b>5</b>, R=<i>n</i>-Bu; <b>6</b>, R=<i>t</i>-Bu). Single-crystal X-ray diffraction studies revealed the tin atoms in both <b>4</b> and <b>6</b> to adopt distorted trigonal bipyramidal configurations with the chlorine atoms occupying the axial positions.<br /><br /><br /> |
