The solventless reaction of diisopropylaminoborane with n ‐butylamine, at room temperature, leads to a mixture of B (sp2) H‐, B (sp3) H 2 ‐, and B (sp3) H 3 ‐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.
