Metal-Free C-B Bond Cleavage: An Acid Catalyzed Three-Component Reaction Construction of Imidazole-Containing Triarylmethanes.

An efficient acid-catalyzed strategy to prepare imidazole-containing triarylmethanes from amidines, ynals, and boronic acids has been developed. It represents an unprecedented and novel metal-free C-B bond cleavage strategy as a workable route to form new carbon-carbon bonds.
