The solventless reaction of diisopropylaminoborane with n‐butylamine, at room temperature, leads to a mixture of B_(sp2)H‐, B_(sp3)H₂‐, and B_(sp3)H₃‐containing species. At low temperature, the reaction outcome is completely modified, thus leading selectively to the formation of high‐mass polybutylaminoborane. When extended to a variety of primary amines, under solventless conditions and at low temperature, this reaction provides a new, efficient, and direct metal‐free access to high‐molecular‐mass polyaminoboranes in good to high yields under mild reaction conditions.

由二异丙基氨基硼烷和伯胺无溶剂无金属合成高分子量的聚氨基硼烷

在室温下，二异丙基氨基硼烷与正丁胺的无溶剂反应会生成含B _（sp2） H-，B _（sp3） H _2-和B _（sp3） H ₃的混合物。在低温下，反应结果被完全改变，从而选择性地导致形成高质量的聚丁基氨基硼烷。当在无溶剂条件下和低温下扩展到多种伯胺时，该反应可在温和的反应条件下以高到高收率提供一种新的，有效的，无金属的高分子量聚氨基硼烷直接接触途径。
