Substituted quinone synthesis by palladium-copper cocatalyzed cross-coupling of stannylquinones with aryl and heteroaryl iodides
摘要:
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.
