At the moment, the synthesis of alkyl amines depends on using ammonia produced by using the Haber-Bosch process and prefunctionalised electrophilic carbon sources.
Here we report the hydroamination of simple alkenes with N2 inside a trititanium hydride framework, which activates both equally alkenes and N2, bringing about selective C‒N bond formation and supplying the corresponding alkyl amines on further more hydrogenation and protonation.
