Porphyrins and metalloporphyrins (or porphyrin coordination complexes) have been wildly investigated as photocatalysts in recent years. Herein we synthesized two new A3B porphyrins, a new asymmetric A3B zinc-porphyrin ligand with peripheral chelate group (pyridine dicarboxylate), and a ruthenium(II) complex of the porphyrin ligand. Their photo-physical properties were characterized and investigated by UV-Vis and fluorescent emission. The modeling of the molecular structures was optimized by DFT theoretical calculation. All porphyrin compounds exhibited strong absorbance at the Soret bands and Q bands. The free base of porphyrin possessed a higher quantum yield and a longer life time than the other two zinc-porphyrins and ruthenium-porphyrin in terms of fluorescence. Furthermore, the ruthenium-porphyrin complex can be used as a promising photocatalyst under visible light for two kinds of organic reactions: ketone-related oxidative aminothiocyanation (above 90% yield) and indole-related oxidative thiocyanation (around 80% yield) with a remarkable low amount (0.1 mmol %).

Paragraph 0066-0069, (2020/06/16)
The invention discloses an application of copper chloride dihydrate in photocatalysis of reaction of an indole compound and a thiocyanate compound. Specifically, under the atmosphere of oxygen or air,an indole compound, an ammonium thiocyanate compound and copper chloride dihydrate are added into a reaction container provided with a stirring device, ethyl alcohol is added, a stirring reaction isconducted for 20-30 hours under room-temperature illumination, and the 3-thiocyanate indole compound is obtained. According to the method, CuCl2.2H2O is directly used as a catalyst for the first timeunder the condition of not adding any photosensitizer. Besides, the efficient preparation of the 3-thiocyanate indole compound is realized, the whole process is green, efficient and easy to operate, and the application is a good method for synthesizing the 3-thiocyanate indole compound.

A low-cost and efficient thio- and selenocyanation strategy for electron-rich arenes has been developed under constant-current electrolytic conditions in an undivided cell. This strategy is versatile for various (hetero)aromatic compounds such as indole, pyrrole, aniline and anisole under mild conditions without any catalyst or oxidant. Readily available salts NH4SCN and KSeCN are employed respectively as the sole reagent.
