Dechalcogenation of Pentachalcogenadistannabicyclo[3.1.1]heptanes

“…The synthesis of trithia-and triselenadimetallabicyclo-[1.1.1]pentanes was accomplished by the dechalcogenation of the corresponding polythia-and poly-selenadimetalla-bicyclo[k.l.m]alkanes (Yoshida et al, 1992;Ando et al, 1995;Choi et al, 1995;Choi et al, 1996;Choi et al, 1997). As for tin analogues, we have recently reported the synthesis, structures and reactions of penta-and tetra-chalcogenadistannabicyclo[k.1.1]alkanes (Saito et al, 2007;Saito et al, 2008). However, no tellurium versions of group 14 [k.l.m]alkanes have been thus far reported.…”
