Abstract
A mild and highly efficient direct synthesis of formanilides from structurally varied arylboronic acids involves a copper-catalyzed Chan-Lam coupling reaction between arylboronic acids and formamide in the presence of a base at room temperature. The strategy offers a valid and practical alternative to existing transformations especially as arylboronic acids are easily accessible, stable, and diversified substrates.
