Summary, etc. |
Two 1,8-naphthyridine derivatives containing methylene, N-(5-methyl-7-((3-oxo-1,3-dihydroisobenzofuran-1-yl)methyl)-1,8-naphthyridin-2-yl)acetamide (<strong>L1</strong>) and 2-amino-3-((7-amino-4-methyl-1,8-naphthyridin-2-yl)methyl)isoindolin-1-one (<strong>L2</strong>), as well as a copper(I) complex CuI(L1)<sub>2</sub> (<strong>C1</strong>) have been synthesized through a non-catalyst C(<em>sp</em><sup>3</sup>)–H methylenation process and characterized. The structure of <strong>C1</strong> has been determined by X-ray diffraction analysis. The spectroscopic properties have been investigated by experimental as well as theoretical studies for all these compounds. The two ligands exhibit similar electronic absorption spectra with λ<sub>max</sub> at about 340 nm, which can be tentatively assigned to π<sub>naph</sub>→π<sub>naph</sub>* transition. The electronic absorption spectra of <strong>C1</strong> exhibits at ~335 nm except in <em>n</em>-hexane, which may be assigned tentatively to the intraligand charge transfer transition. The assignment is further supported by density functional theory calculations and cyclic voltammetry. |
