A simple and efficient direct radical C-2 arylation of 3-aminochromone derivatives with aryl hydrazine is described. The aryl hydrazine acts as an initiator and source for the aryl radicalvia the cleavage of the C–N bond of aryl hydrazine. The reaction proceeds via a base-promoted single electron transfer (SET) pathway. The aryl radical abstracts a single electron from 3-aminochromone, which generates
