With
triphenylphosphine oxide serving as both the directing group
and the reagent, we have developed a Cp*Ir(III)-catalyzed direct C–H
functionalization of triphenylphosphine oxide with 3-diazooxindoles
to afford a range of 3-(2-(diphenylphosphoryl)phenyl)indolin-2-one
derivatives in moderate to excellent yields. The title products are
potentially important building blocks for organic synthesis through
various chemical transformations. This
protocol is simple and efficient and offers high atom economy with
only N2 as the byproduct.
