摘要：

New Iminoboranes R-B=N-R' (R = 2,4,6(t-Bu)3C6H2, IIa - IIf, were obtained by base-induced HF-elimination from RBF-NHR' (Ia - Ie) or directly from RBF2 and lithiated H2NR' (for IIf). Compounds II exhibit a differentiated behaviour upon thermal treatment depending on R'. While II a (R' = H) immediately reacts to give the corresponding benzo[1]borolane IIIa, the dimeric diazadiboretidine is formed from 11 b (R' = Me) at 100-degrees-C; IIc (R = Et) and IId (R = C6H5) deliver the benzo[1]borolanes IIIc and IIId when they are heated to 180-degrees-C (in melt). IIe (R = 2,6(i-Pr)C6H3) and IIf (R = adamantyl) are stable at 250-degrees-C. All compounds were characterized by elemental analyses and spectroscopically (MS, IR, NMR: H-1, C-13, B-11, F-19 and in part N-15).
