The direct CH benzylation of azoles with benzyl chlorides proceeds efficiently, via sequential cleavage of one sp2 CH bond and two sp3 CHbonds in the presence of a palladium catalyst, to generate a wide range of tribenzylated azoles with a quaternary carboncenter efficiently. The same catalyst could also promote the mono‐ and di‐benzylation reactions through fine turning of the base and reaction
According to one embodiment of the present disclosure, a method of forming an ultraviolet-stabilized corrosion inhibitor is provided. The method includes forming a functionalized azole; forming a functionalized photosensitizer; and forming an ultraviolet-stabilized corrosion inhibitor by reacting the functionalized azole with the functionalized photosensitizer. In another embodiment, an ultraviolet-stabilized corrosion inhibitor is provided. The inhibitor includes an azole bonded to a photosensitizer. In another embodiment, an article of manufacture is provided. The article of manufacture includes a material comprising a reaction product of an azole and a photosensitizer.
