DOI: 10.1039/c7nj04342b
Abstract: A novel three-component assembly of allenic alcohols, aryl iodides and 1,3-dicarbonyl compounds into 3,3-disubstituted allylic alcohols was promoted in the presence of a palladium source. A plausible mechanism through Pd0 catalysis was established to explain… read more here.
