Abstract: The bulky m-terphenyl phenol Ar*OH 1 (Ar* = [C.sub.6][H.sub.3]-2,6-[Mes.sub.2], Mes = 2,4,6-trimethylphenyl) was synthesized via the treatment of Ar*Li with nitrobenzene. The phenol 1 is prepared in modest to good yield using this method. Attempts were also made to prepare 1 through oxidation of the bulky boronic acid Ar*B[(OH).sub.2] with Oxone[R] but this reaction was not suitable for preparative-scale reactions. Side products of the reaction between Ar*Li and nitrobenzene were identified as Ar*[N(O)Ph] and [[[C.sub.6][H.sub.5]N(O)].sub.2] and were characterized by X-ray crystallography and EPR spectroscopy. A variety of main-group and transition-metal ...
