A method for the electrochemical arene C(sp2)—H bromination of glycine derivatives at room temperature is reported. Under mild reaction conditions, a series of brominated N-aryl glycine amides, N-aryl glycine esters, and dipeptide at aromatic C(sp2)—H bonds were smoothly synthesized using tetrabutylammonium bromide or tetrabutylammonium tribromide as Br sources and electrolytes with up to 95% yield. Compared with traditional methods, this methodology features broad substrate scope, good functional group compatibility, easy operation, without using additional oxidants and metal catalysts, thus much conforms to the requirement of green chemistry and environmental protection.

Key words: glycine derivative, organic electrosynthesis, C—H activation, bromination reaction
