An unprecedented KHMDS-promoted domino reaction to furnish hydroxyfluoranthenes is described. Biaryl compounds bearing acyl and naphthylalkenyl moieties are transformed into 9-hydroxydibenzo[j,l]fluoranthenes in a single step through the formation of an aromatic and a pentagonal ring system. A variety of fluoranthenes including those with extended π-conjugation, a heteroaromatic ring, and unsymmetrical
ortho-Selective C–H borylation of aryl ketones with bis(pinacolato)diboron proceeded at 120 °C in octane in the presence of a catalytic amount of iridium(I) complexes comprising 1/2[Ir(OMe)(cod)]2 and AsPh3.
