Abstract: Abstract The three Cu(I) complexes [Cu(POP)(N^N)]PF6, N^N = 2-(1H-imidazol-2-yl)-5-(p-tolylethynyl)pyridine (P1), 2-(1H-imidazol-2-yl)-5-((4-methoxyphenyl)ethynyl)pyridine (P2), 4-((6-(1H-imidazol-2-yl)pyridin-3-yl)ethynyl)-N,N-diphenylaniline (P3), were prepared and characterized. The different electron-donating groups such as methylphenyl, methoxyphenyl, and diphenylamine substituents were functionalized onto the pyridine ring part of… read more here.

Abstract: Enones with β-electron-donating groups can exist in their zwitterionic resonance forms, which favor nucleophilic attack to phosphenes generated from phosphoryl (aryl)diazomethanes under blue light irradiation to yield zwitterionic intermediates. The intermediates cyclize to afford highly… read more here.
