Abstract
A chromium-catalyzed activation of acyl C-O bonds with magnesium enables an amidation of esters with nitroarenes in the presence of chlorotrimethylsilane as additive. The reaction provides a step-economic strategy to the synthesis of important amide motifs using inexpensive and air-stable nitroarenes as amino sources.
