Sažetak
Recent evolution of solid-state synthetic methods has led to their prompt utilization in a metalcatalyzed functionalization of organics. An important class of catalytic reactions are palladiummediated processes for which the C–H bond activation is identified as the first mechanistic step in a solution. However, a mechanistic study of the solid-state C–H bond activation is still lacking. We have studied a mechanism of the ligand- directed C–H bond activation by various Pd(II) catalysts under mechanochemical conditions by in situ Raman monitoring and ex situ PXRD, NMR and IR methods. Selected Pd(II) precursors, PdCl2, PdCl2(MeCN)2, [Pd(MeCN)4][BF4]2 and [Pd(OAc)2]3, have been employed for solid-state activation of C–H bonds in an azobenzene substrat. Raman monitoring has provided direct probing of the reaction mechanism and revealed how liquid (DMF, MeCN, AcOH and H2O) as well as solid additives (NaOAc and NaBF4) influence the reactions.
