| Popis: | The bifunctional 1,3-dichloro-tristannane CltBu2Sn-SntBu2-SntBu2Cl, 1, has been investigated with respect to thermolysis and nucleophilic substitution. Thermolysis of 1 leads to slow elimination of the stannylene which may be trapped by elemental sulphur, PhSSPh and 2,3-dimethylbutadiene. Reactions of 1 with the silyllithium reagent PhMe2SiLi, lead to new group 14 catenanes PhMe2Si-SntBu2-tBu2Sn-SntBu2-Cl, 9, and PhMe2Si-SntBu2-tBu2Sn-SntBu2-SntBu2-SiPhMe2, 10. Both 9 and 10 have been characterized by single crystal X-ray diffraction. Overall the new chemistry illustrates the significance of tBu2Sn: during such reactions, either loss or addition! |
