Herein, we report a transition metal‐free, operationally simple, general method for straightforward syntheses of 2‐substituted benzoxazoles from readily available cyclohexanones and aliphatic primary amines by an imine α‐oxygenation‐initiated cascade reaction sequence. The key to achieving high selectivity and excellent functional‐group tolerance is the use of TEMPO as a mild oxidant that selectively...
Diazaphospholenes are widely used as hydride transfer catalysts, however their use in radical reactions is a recently emerging area. Here, we show prior stoichiometric radical cyclizations of aryl iodides mediated by diazaphospholene hydrides are made catalytic by the combination of phenylsilane and alkali metal salts to regenerate the diazaphospholene hydride. The scope was expanded to include aryl...
