A simple and efficient method for the synthesis of diaryl 1,2-diketones has been developed. The reaction represents the first example of diaryl 1,2-diketones that are synthesized directly from arylboronic acids and arylpropiolicacids by a radical pathway in moderate to good yields. This reaction proceeds under mild reaction conditions and with good tolerance of a variety of functional groups. Preliminary

An efficient one-pot synthesis of various unsymmetrical benzils via N-heterocyclic carbene (NHC)-catalyzed aroylation of N-phenylimidoyl chlorides with aromatic aldehydes followed by acidic hydrolysis has been developed. The one-pot procedure was extended to synthesis of quinoxalines and pyrazines by condensation/annulation of unsymmetrical benzils generated in situ with diamines.
