Substituted Quinone Synthesis by Palladium-Copper Cocatalyzed Cross-Coupling of Stannylquinones with Aryl and Heteroaryl Iodides

Article abstract of DOI:10.1021/jo00054a025

A general and high-yielding route to a variety of aryl- and heteroaryl-substituted quinones is now available via the palladium-copper cocatalyzed cross-coupling of stannylquinones with aryl and heteroaryl iodides.Using this technology a number of novel aromatic- and heteroaromatic-substituted quinones were produced.Mechanistic insight is presented into the various catalytic systems used.
