Cu-catalysed arylation reactions devoted to the formation of C–C and C–heteroatom bonds
(Ullmann-type couplings) have acquired great importance in the last decade. This review …

The chemistry of copper is extremely rich because it can easily access Cu0, CuI, CuII, and
CuIII oxidation states allowing it to act through one-electron or two-electron processes. As a …

Ullmann-type C–N coupling reactions represent an important alternative to well-established
Pd-catalyzed approaches due to the differing reactivity and the lower cost of Cu. While the …

Copper‐catalyzed Ullmann condensations are key reactions for the formation of carbon–
heteroatom and carbon–carbon bonds in organic synthesis. These reactions can lead to …

Natural product synthesis is a highly demanding field in constant need of efficient
transformations that allow either straightforward, scalable, and high-yielding preparation of …

The C–N cross-coupling chemistry intensely developed since the late 1990s has supplied
synthesists with an overwhelming number of methods to effectively combine carbon and …

The utility of copper-mediated cross-coupling reactions has been significantly increased by
the development of mild reaction conditions and the ability to employ catalytic amounts of …

Organometallic CuIII species have been invoked in many copper-catalyzed reactions, but
until recently, experimental evidences were lacking. The advent of new spectroscopic …

The copper-mediated aromatic nucleophilic substitution reactions developed by Fritz
Ullmann and Irma Goldberg required stoichiometric amounts of copper and very high …

A general method for the formation of benzoxazoles via a copper-catalyzed cyclization of
ortho-haloanilides is reported. This approach complements the more commonly used …
