Silver-catalyzed P-centered anion nucleophilic addition to isocyanide: Access to 2-phosphinoyl indoles/indol-3-ols

A silver-catalyzed P-centered anion-initiated cascade reaction of functionalized arylisocyanides with H-phosphorus oxides was established for the expeditious synthesis of various 2-phosphinoyl-indole/-indol-3-ol derivatives.
