2,4,6-Tri-t-butylphenyl-substituierte Iminoborane

Iminoboranes RBNR' : IIb (R' = t-Bu) and IIc (R'= SiMe3) carrying the supermesityl group (R) on the boron atoms have been prepared by thermal elimination of fluorotrimethylsilane from the relevant fluoro(trimethylsilylamino)borane precursors Ib and Ic.The intermediate IIa (R' = i-Pr) rearranges to give the benzoborolane derivative IIIa.However IIa (and also IIb) are obtained by HF-elimination with t-BuLi from the corresponding fluoro(amino)boranes IVa and IVb at low temperature, the iminoboranes IIa-IIc are thermally stable at temperatures of more than 200 deg Cand the benzoborolanes IIIb and IIIc are formed at 350 and 250 deg C, resp.H acidic compounds HX (X =OH, O-t-Bu, HN-t-Bu,Cl) are readily added to IIc to give aminoboranes Va-Vd.The iminoborane VII: t-Bu-BNR was prepared from F2BNHR (VI) and two moles t-BuLi.The compounds are characterized by elemental analyses and spectroscopic data (MS, IR, NMR: 1H, 11B, 13C, 15N, 17F, 29Si).X-ray diffraction studies have been performed on IIb and Va.
