Abstract

Abstract: Transition metal‐catalyzed ortho‐ selective C( sp 2 )−H amidation of weakly coordinating aldehydes remains limited to precious metals such as Ir, Rh, Ru, etc. Herein, we put forward a novel report on ortho‐ amidation of benzaldehydes employing user‐friendly dioxazolones under cost‐effective and air‐stable Cp*Co(III) catalysis. This catalytic transformation involves transient directing group strategy to enhance the ligating capability of weakly chelating aldehydes. Abstract :
