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.

主体试剂对BN三键的裂解†

我们报告了两个罕见的情况下插入到亚氨基硼烷的强（约170 kcal mol ^-1）BN三键中。首先，将亚甲硅烷基插入二叔丁基亚氨基硼烷中以形成亚氨基硅烷。在第二个反应中，可以迫使高度拥挤的亚氨基硼烷Ter-NB-TMP（TMP = 2,2,6,6-四甲基哌啶基，Ter = 2,6-（二苯甲基）-4-叔丁基苯基）与Pip–反应。 CC–Pip（Pip =哌啶基）在60°C下。反应产物是将Pip–CC插入亚氨基硼烷BN键中的明显结果。
