Abstract

No compass required: A method is described for forming biaryl CC bonds by a PdII-catalyzed cross-coupling of aryl CH bonds with aryl boronic acids under mild conditions without the presence of directing groups. Different substituents on both (hetero)arenes and aryl boronic acids are compatible with the reaction conditions, and the homocoupling of boronic acids is highly inhibited. Dioxygen was applied as the final oxidant. Supporting information for this article is available on the WWW under http://www.wiley-vch.de/contents/jc_2002/2008/z704619_s.pdf or from the author.
