Bismuthanylstibanes

Thermally-robust bismuthanylstibanes are prepared in a one-step, high yield reaction, providing the first examples of neutral Bi-Sb σ-bonds in the solid state. DFT calculations indicate that the bis(silylamino)naphthalene scaffold is well-suited for supporting otherwise labile bonds. The reaction chemistry of the Bi-Sb bond is debuted by showing fission using NH 3 BH 3 and insertion of a sulfur atom, the latter providing the first example of a Bi-S-Sb motif. The first examples of neutral Bi-Sb σ-bonds are reported and their reactivity is debuted.
