Abstract
A mild and efficient method for the synthesis of 3-difluoroacetylated coumarins through visible-light-promoted aryldifluoroacetylation of alkynes with ethyl bromodifluoroacetate has been developed. The reaction allows the direct formation of Csp(2)-CF2COOEt and C-C bonds via a proposed tandem radical cyclization process.
