Below we report the hydroamination of simple alkenes with N2 in the trititanium hydride framework, which activates each alkenes and N2, bringing about selective C‒N bond development and supplying the corresponding alkyl amines on further more hydrogenation and protonation. Computational scientific studies expose crucial mechanistic aspects of N2 activation and selective C‒N bond formation. This operate demonstrates a method to the transformation of N2 and easy hydrocarbons into nitrogen-containing organic and natural compounds mediated by a multinuclear hydride framework.
