Unprotected amine transfer performed by non-heme iron(II) complexes
Autor: Alizée Boullé, Aminata Doumbia, Jean-Pierre Mahy, Frédéric Avenier
Publikováno v: Chemical communications (Cambridge, England).
Direct amination of C-H or CC bonds using unprotected amino groups is very challenging, especially with earth abundant metal ions. Here we show that a bioinspired iron(II) complex catalyses the double amination of its dangling benzyl branch in the
