successfully achieved by using a catalytic amount of Pd(OAc)2 (min. 1 mol%). The catalyst showed excellent catalytic performance under CO/CO2-binary conditions, and the use of p-benzoquinone (p-BQ) as a stoichiometric oxidant for the regeneration of high-valent palladium catalysts active for C–H bond activation of heteroaromatics successfully led to the corresponding carboxylicacids in up to quantitative
