The Pd-catalyzed C–H activation of natural tryptophanresidues has emerged as a promising approach for their direct synthetic modification. While usingwater as the solvent and harnessing air as the oxidant is enticing, these conditions induce catalystdeactivation by promoting the formation of inactive Pd(0) clusters. In this work, we have studied optimized Pd-based catalytic systems via nonsteady
