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
