The combination of 20 mol % of copper iodide and lithium tert‐butoxide triggers the formation of a broad range of substituted, functionalized α‐alkoxy 2H‐naphthalenones from readily available N‐tosylhydrazones. The data suggests that this transformation occurs through cycloaddition of a copper carbenoid with an ester, followed by a Lewis acid‐catalyzed [1,2] alkyl shift of the in situ generated alkoxyepoxide
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.
