A heterogeneous photocatalyst based on copper modified phosphorus doped g-C3N4 (Cu/P-CN) has been prepared and characterized. This recyclable catalyst exhibited high photocatalytic activity for the synthesis of N-arylpyridin-2-amine derivatives I (Ar = Ph, naphthalen-1-yl, thiophen-3-yl, dibenzo[b,d]furan-3-yl, etc.; R = H, Me; R1 = H, Cl, Br, Me, NO2; R2 = H, Cl, Br, Me; R3 = H, Cl, Br) by the reaction of 2-aminopyridines II and aryl boronic acids ArB(OH)2 at room temperature under the irradiation of blue light. Importantly, the range of substrates for this coupling reaction has been expanded to include aryl boronic acids with strong electron-withdrawing groups as viable raw materials. In addition, this heterogeneous catalyst can be used at least 6 times while maintaining its catalytic activity. In the part of experimental materials, we found many familiar compounds, such as Pyridin-3-ylboronic acid(cas: 1692-25-7Safety of Pyridin-3-ylboronic acid)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.Safety of Pyridin-3-ylboronic acid
