Ni(OAc)2 Catalyzed N‐Formylation of Primary Sulfonamides Using Carbon Dioxide at Ambient Pressure
Von Wiley-VCH zur Verfügung gestellt
A Ni(OAc)2 catalysed N-formylation of primary sulfonamides using gaseous carbon dioxide is reported. A range of aromatic, heteroaromatic, and aliphatic sulfonamides were formylated under ambient pressure of carbon dioxide in a closed system. This redox neutral method represents a mechanistically novel and operationally convenient method for employing carbon dioxide as a formyl equivalent.
