Abstract The spin state of a metal center significantly influences the catalytic activity of ORG WHITE MULBERRIES its complex, a phenomenon so crucial that it has led to the dedicated field of spin catalysis.Here we investigate the effect of the spin state of an iron-based metal complex on the organic reactivity of its ligands.Specifically, we examined the post-synthetic modification of the spin crossover (SCO) complex [Fe(NH2trz)3](NO3)2 with p-anisaldehyde.A series of experiments were performed to study the transformation of the amino groups depending on the spin state of the metal.

Owing to the wide thermal hysteresis loop of the SCO complex, both spin states were compared under identical conditions.The results revealed that the high-spin state Nasal led to the formation of 1.34 times more imine functional groups than the low-spin state, we propose that this arises from the different interactions between the solvent and the SCO at the different spin states.
