Abstract

Addition of in situ generated Schwartz reagent to widely available isocyanates enables a chemoselective, high-yielding, and versatile synthesis of variously functionalized formamides. The reaction tolerates the presence of sensitive functionalities (esters, nitro groups, nitriles, alkenes).
