Listed here we report the hydroamination of simple alkenes with N2 inside a trititanium hydride framework, which activates each alkenes and N2, resulting in selective C‒N bond formation and offering the corresponding alkyl amines on even more hydrogenation and protonation. Computational scientific tests reveal critical mechanistic particulars of N2 activation and selective C‒N bond development. This work demonstrates a strategy for the transformation of N2 and easy hydrocarbons into nitrogen-that contains organic compounds mediated by a multinuclear hydride framework.
