DOI: 10.1021/jacs.2c04621
Abstract: Aromatic C–H activation in alkylarenes is a key step for the synthesis of functionalized organic molecules from simple hydrocarbon precursors. Known examples of such C–H activations often yield mixtures of products resulting from activation of… read more here.

DOI: 10.1039/c6qo00834h
Abstract: Pd(OAc)2-catalyzed direct C–H arylation of an arene triazole template has been explored using the triazole ring as a directing group. The N(3)-ortho C–H bond on C(4) aryl of 1,4-disubstituted 1,2,3-triazoles can be selectively arylated, exclusively… read more here.
