A simple and efficient Pd-catalyzed method for the C2-acylation of indoles is described. Less toxic, stable, and commercially available toluene derivatives were used as acyl sources, with tert-butylhydroperoxide (TBHP) as oxidant and pivalic acid as additive, providing moderate to good yields. © 2017 The Royal Society of Chemistry.
