A versatile method for the rapid synthesis of diverse functionalized pyrazolines has been developed based on copper-mediated aminofunctionalization of β,γ-unsaturated hydrazones. The scope of this strategy encompasses a range of difunctionalization reactions: aminoazidation, aminohalogenation, and aminothiocyanation. These reactions provide straightforward access to a series of useful pyrazoline building blocks containing various functional groups that are hard to access traditionally.

Photo-induced variation of magnetism from ligand-based electron transfer have been extensively studied because of their potential applications in magneto-optical memory devices, light-responsive switches, and high-density information storage materials. In this...
