A novel photocatalyzed radical addition/oxygen oxidation/cleavage of dioxetane/hydrogen atom transfer domino process for cleavage of CC bonds has been described. This protocol used porous graphitic carbon nitrides (p-g-C3N4) as a metal-free recyclable photocatalyst for transformations of alkynes RC6H4CC with diazonium salts R1C6H4N+N.BF4- to give two different aldehydes RC6H4CHO, R1C6H4CHO or esters RC6H4C(O)OMe, R1C6H4C(O)OMe, which enables the formation of multiple C-O bonds in a single reaction with operational simplicity. This reaction has an excellent substrate scope and gives the desired products in moderate to high yields. In addition, the heterogeneous semiconductor exhibits easy handling and excellent recyclability for at least 6 cycles without any apparent loss of activity. Furthermore, this reaction could be carried out under solar light irradiation and is applicable for the gram scale with satisfactory results. In the experiment, the researchers used Methyl 4-fluorobenzoate(cas: 403-33-8Application of 403-33-8)
Methyl 4-fluorobenzoate(cas: 403-33-8) is an organic fluorinated building block used for the synthesis of various pharmaceutical compounds. It can be used for the preparation of Blonanserin.Application of 403-33-8
