“…Usually by dehydration of diols, the α‐diketones were prepared often, but various methods have been put forward afterwards. Diverse metal catalysed such as, Pd, Ru, Fe, Cu, Mn, Au, Mo, Hg, used processes that have received considerable attention for the synthesis of α‐diketones from different sources. Despite this progress with transition metals, acid catalysts and oxidizing agents, were used in numerous methodologies by the researchers.…”
