Mechanistic insight into solid-state C-H bond activation in azobenzene by palladium(II) chloride

The recent advances of solid-state synthetic methods led to their application in the synthesis of palladacycles via C-H bond activation, a process known as cyclopalladation. Since palladacycles are crucial intermediates in many organic reactions mediated by palladium catalysts, a thorough understanding of cyclopalladation pathways of different organic substrates is essential. In contrast to the mechanism of palladation that is widely explored in solutions, a mechanistic study of the solid-state C–H bond activation is still in its early stages. We have studied a mechanism of the ligand-directed C–H bond activation in azobenzene with palladium(II) chloride under mechanochemical conditions by in situ Raman monitoring and ex situ 1H-NMR spectroscopy. In situ Raman monitoring revealed that solid-state dicyclopalladation azobenzene is a multi-step process including the formation of coordination and monocyclopalladated species as intermediates. Our results indicated that the mechanism of solid- state dicyclopalladation of azobenzene differs from that observed for the analog reaction in solution.
