Özet

This study presents a facile method for synthesizing urethanes through the photocatalyzed oxidative decarboxylation of oxamic acids. The process involves the in-situ formation of an isocyanate from oxamic acid under blue light irradiation (427 nm) and in the presence of ferrocene as a photocatalyst, 2-picolinic acid as a ligand and potassium bromate as an oxidant. The one-pot procedure effectively avoids the need for separation, purification, and storage of carcinogenic isocyanates, making it a safer and more practical method for obtaining target urethanes from easily accessible starting materials.
