Radical Carbonylation under Low <scp>CO</scp> Pressure: Synthesis of Esters from Activated Alkylamines at Transition <scp>Metal‐Free</scp> Conditions

Abstract

Main observation and conclusion High CO pressure (&gt; 40 bar) is usually needed in radical carbonylation reactions in the absence of metal catalyst. In this communication, we developed a transition‐metal‐free radical carbonylation of activated alkylamines with phenols and alcohols under low CO pressure (1—6 bar). Various esters were obtained in moderate to excellent yields under simple reaction conditions with good functional group compatibility.
