The conversion of N,N′-dilithiobis(alkylamido)phenylboranes [RN–BPh–NR]Li2 (R = tBu (1), iPr (2)) to the equivalent dithallium(I) bisamides proceeds readily through the reaction with two molar equivalents of thallous chloride. The thallium amides [RN–BPh–NR]Tl2 (R = tBu (3), iPr (4)) have been prepared and characterized by 1H and 11B{1H} NMR. Single crystal X-ray structures of 2–4 reveal the formation of aggregates in the solid state.
Graphical abstractLithium and thallium(I) complexes of bis(alkylamido)phenylborane ligands, [RN–BPh–NR]M2 (R = tBu, iPr; M = Li, Tl), have been prepared and characterized by 1H and 11B NMR spectroscopy. Single crystal X-ray structure analysis demonstrates interesting aggregation in the solid state. The bis(tert-butylamido)phenylborane complex of thallium(I) is shown.Figure optionsDownload full-size imageDownload as PowerPoint slide
