Abstract

Ullmann condensation using Cu or copper oxide as the reactant and using no base has been studied. Reactions of active NH, OH, and CH compounds, RZH (imides, amides, amines, phenol, benzoic acid, and phenylacetylene), with mixtures of aryl halides and more than a stoichiometric amount of Cu or copper oxide (Cu2O or CuO) without addition of base lead to facile arylation of the active hydrogen compounds. In the arylation reaction Cu and ...
