We first investigated possible curing reactions occurring in the studied thermoset at the DLPNO-CCSD(T) /def2-QZVPP 50 // wB97xD 51 /def2-TZVP 52 level of theory. For further details on these calculations please refer to Section S2 of the Supporting Information. Briefly, in line with the DFT calculations of Ehlers et al., who found that the reaction favors a step-wise rather than a concerted reaction (Figure ), we predicted similar reaction kinetics for model systems involving primary and secondary aromatic amines, as shown in Scheme 4. The obtained energetic barriers (Table )
