A selective, economical, and ecol. protocol has been described for the oxidation of Me arenes and their analogs ArCH2R (Ar = 3-nitrophenyl, 1-naphthyl, furan-2-yl, etc.; R = H, Me, Ph, pyridin-2-yl) and 9H-fluorene to the corresponding carbonyl compounds ArC(O)R and 9H-fluoren-9-one and epoxidation reactions of alkenes, e.g., 1,3-cyclohexadiene with mol. oxygen (O2) or air as a green oxygen source, under mild reaction conditions. The nano Ni/g-C3N4 exhibited high photocatalytic activity, stability, and selectivity in the C-H activation of Me arenes, methylene arenes, and epoxidation of various alkenes under visible-light irradiation without the use of an oxidizing agent and under base free conditions. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Category: pyridine-derivatives).
Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Category: pyridine-derivatives
