The selective, one step oxidation of 2,3,6-trimethylphenol (TMP) to 2,3,6-trimethyl-1,4-benzoquinone (TMQ) by a catalytic amount of CuClz (up to 100 turnovers) and NH,OH . HCl has been investigated. TMQ was obtained in up to 80% yield using only 1.5 wt% CuC12 catalyst (related to the amount of TMP)
## Abstract Taking the regioβ and chemoselectivities of our iron complex precursors with pyridine core in aerobic oxidations into account, we envisioned a more effective influence on catalytic properties by the introduction of different substituents in 4βposition of the pyridine moiety. The synthes
