converter gas can be used as a reducing agent in organic reactions to produce valuable pharmaceuticals and agrochemicals. In particular, amide-based selected drug molecules have been synthesized by a reaction of aromatic nitro compounds and carboxylicacids in the presence of converter gas. In addition, we showed that this gas can also be conveniently utilized to carryout classical reductive amination reaction
An Fe(III)-catalysed transformation of secondary N-phenyl substituted amides to primary amides by an electrochemical method is developed. Regioselective aryl C–H oxygenation occurs during the reaction, promoting selective C(phenyl)-N bondcleavage to form primary amides in yields of up to 92%.
开发了一种通过电化学方法将 Fe( III ) 催化的仲N-苯基取代酰胺转化为伯酰胺的方法。反应过程中发生区域选择性芳基 C-H 氧合,促进选择性 C(苯基)-N 键裂解形成伯酰胺,产率高达 92%。
