These copper loaded microgels are an interesting platform and for future application more challenging copper catalyzed reactions were investigated in this work. Therefore, the aziridination of styrene derivatives and the C\u2500H amination reaction catalyzed by copper bis(pyrazolyl)methane complexes were performed. For both reactions good yields were achieved and challenging substrates, like benzene or cyclohexane, could be converted. The central intermediates of these reactions are copper nitrene complexes. The copper nitrene complexes could be stabilized at low temperature and analyzed with different spectrometric methods and with DFT calculations. It could be shown that the ligand design has a huge influence on the stability and reactivity of the copper nitrene complexes. Furthermore, the mechanism of the aziridination was investigated experimentally and theoretically.<\/p>\n\n\n\n<p><em>Fabian Thomas, Matthias Oster, Florian Sch\u00f6n, Kai C.
