High‐molar‐mass poly(alkylphosphinoboranes) are currently not accessible by conventional metal‐catalyzed dehydropolymerization. However, the mild thermolysis of a Lewis base stabilized phosphinoborane is an alternative metal‐free approach. In their Communication on page 13782 ff., M. Scheer, I. Manners, and co‐workers describe their successful synthesis of poly( tert ‐butylphosphinoborane) by this promising strategy.
