α,β-Diaryl unsaturated ketones via palladium-catalyzed ring-opening of cyclopropenones with organoboronic acids

Palladium-catalyzed ring-opening acylation of cyclopropenones with organoboronic acids (aryl and vinylboronic acids) at room temperature has been developed to synthesise α,β-diaryl unsaturated ketones with good yields and excellent stereospecificity.
