我们报告了两个罕见的插入亚胺硼烷的强(约170千卡·摩尔-1)BN三键的例子。在第一种方法中，硅烯插入到二叔丁基亚胺硼烷中形成亚氨基硅烷。在第二个反应中，高度拥挤的亚胺硼烷Ter-Nb-TMP(TMP=2，2，6，6-四甲基哌啶，Ter=2，6-(二苯甲基)-4-叔丁基苯基)在60℃下与Pip-CC-Pip(Pip=哌啶基)发生反应，反应产物是Pip-CC插入亚胺硼烷BN键的明显结果。
We report two rare instances of an insertion into the strong (ca. 170 kcal mol-1) BN triple bond of iminoboranes. In the first, a silylene inserts into di-tert-butyliminoborane to form an iminosilane. In the second, the highly crowded iminoborane Ter-NB-TMP (TMP = 2,2,6,6-tetramethylpiperidyl, Ter = 2,6-(diphenylmethyl)-4-tert-butylphenyl) can be forced to react with Pip-CC-Pip (Pip = piperidyl) at 60 °C. The reaction product is the apparent result of Pip-CC insertion into the iminoborane BN bond.
