Directed tris-ortholithiation of tris[2-(diethylaminosulfonyl)phenyl]bismuthane 1 with tert-butyllithium followed by treatment with 3 equiv. of bis[2-(diethylaminosulfonyl)-phenyl]bismuth iodide 2a gives a symmetrically branched Bi4-bismuthane 5a, which, on a similar treatment, is converted in a one-pot synthesis into a highly branched Bi10-bismuthane 6a.
