Tri-Substituted Triazole-Enabled C-H Activation of Benzyl and Aryl Amines by Iron Catalysis.

The design of trisubstituted triazoles set the stage for proximity-induced iron-catalyzed C-H activation of benzyl and aryl amines with ample scope. Thereby, C-H alkylations and C-H arylations proved viable with high levels of chemo and positional selectivities by means of racemization-free iron catalysis with the reusable triazole being removed in a traceless fashion.
