Abstract / Bemerkung
In this contribution we report on the synthesis of bis(pentafluoroethyl)stannane, H2Sn(C2F5)(2). In the reaction with donor molecules a ready elimination of hydrogen and the formation of the corresponding donor-stabilized monomeric bis(pentafluoroethyl)stannylene, Sn(C2F5)(2), becomes apparent. With dependence on the Lewis basicity and steric demand of the donor, varying coordination numbers are realized. Whereas the reaction with nitrogen bases like 4-(dimethylamino)pyridine (DMAP) leads to the complexation of two donor molecules, [Sn(C2F5)(2)(dmap)(2)], treatment with PMe3 or [Sn(C2F5)(3)](-) furnished the corresponding neutral or anionic monoadducts, [Sn(C2F5)(2)(D)] (D=PMe3, [Sn(C2F5)(3)](-)). In contrast, the utilization of sterically demanding donors, such as iPr(2)O, as well as the thermal treatment of ether complexes, [Sn(C2F5)(2)(D)(n)] (D=Et2O, THF), leads to the formation of oligomeric and cyclic stannylene moieties [Sn(C2F5)(2)](n). The reactivity of H2Sn(C2F5)(2) and the donor-stabilized stannylenes was proven by hydrostannylation and complexation reactions with tetracarbonylnickel and bimetallic compounds. In the latter case, a donor-dependent stannylene or distannylene insertion into the metal-metal bond was observed.
