In recent years, there has been a constant drive for greener and sustainable chemistry. As such, a novel methodology has been employed to achieve the decarboxylative allylation of nitro-arene allyl esters using an earth-abundant metal, cobalt. The reaction allows for the formation of various substituted allylated products in excellent yields with a broad scope on either reaction partner, generating carbon dioxide as the only by-product. The Co(II)/dppBz precatalyst is activated by the carboxylate salt under the reaction conditions to generate a Co(I)-species, which is presumed to be the active catalyst. Further investigations of the catalyst system are underway.
