The nanomaterial containing amphiphile-stabilized mononuclear Cu(II) is developed. The material is characterized by various spectroscopic techniques, such as X-ray absorption spectrscopy (XAS), high-resolution transmission electron microscopy, NMR (NMR), UV-vis, and IR spectroscopies. Since the structural data for the amphiphile-bound Cu(II) center is not available, a theor. model based on DFT calculations is employed. The analyses based on NMR spectroscopic data, including the isotope labeling, support that the tertiary amide group of the amphiphile binds to the Cu surface. Likewise, the bond distances found by XAS spectroscopy agree with the theor. model. Time-dependent DFT studies predict that the low-lying excited state has a dominant ligand-to-metal charge transfer (LMCT) character. Cu(II) changes to Cu(I) assisted by the LMCT excitation upon visible light irradiation, generating robust catalytically active species. The catalytic activity for domino azidation-[3+2] cycloaddition reactions in water is investigated. The catalytic protocol is applicable on various substrates, and the catalytic material is stable under ambient conditions for up to three months. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3Synthetic Route of C5F5N).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Synthetic Route of C5F5N
