Access to 1: H -indazoles, 1 H -benzoindazoles and 1 H -azaindazoles from (het)aryl azides: A one-pot Staudinger-aza-Wittig reaction leading to N-N bond formation?

The synthesis of various substituted 1H-indazoles is reported through N-N bond formation from an iminophosphorane derivative. Supported by control experiments, an original Staudinger-aza-Wittig tandem mechanism is proposed for this transformation.

Synthesis of 2-aryl-3-arylsulfonylindoles and 2-anilino-3- arylsulfonylindoles from 2-(arylsulfonyl)methylanilines using the aza-Wittig reaction of iminophosphoranes

2-(Arylsulfonyl)methyl-N-(triphenylphosphoranylidene)-anilines 5 were prepared starting from 2-(arylsulfonyl)-methylanilines 2. The aza-Wittig reaction of iminophosphoranes 5 with acyl cyanides gave N- [aryl(cyano)methylene]-2-(arylsulfonyl)methylanilines
