Ullmann Reaction - The Ullman reaction is a named reaction that involves the coupling of two aryl halides with the help of copper.

The Ullmann reaction or Ullmann coupling, named after Fritz Ullmann, couples two aryl or alkyl groups with the help of copper. The reaction was first ...

Copper-catalyzed cross-couplings of aryl halides and nucleophiles, traditionally called Ullmann-type coupling reactions, were initially ...

As early as 1901, Ullmann reported the first copper-mediated coupling reaction, in which two aryl iodides were coupled to form the biaryl product by consuming ...

This Account details the development of the palladium-catalyzed Ullmann cross-coupling reaction as a useful method for the assembly of a range ...

The modified Ullmann reaction between aryl iodide and amines or primary alcohols proceeds either via an SET or an IAT mechanism.

They improve antibacterial serum properties by increasing the level of natural antibodies. If needed, these reactions should be easily ...

The Ullmann reaction is a copper-promoted homo- or hetero-coupling between two aryl halides 〈74S9〉 . 2,2′-Bipyrimidine (212) 〈62JOC2945〉 and 4,4′-diphenyl-2,2′-bipyrimidine 〈67JOC1591〉 can be prepared from the corresponding 2-bromopyrimidine by Cu-me

The condensation of two aryl halides in the presence of copper to create biaryl products is now known as the Ullmann reaction. Since then, many differing ...
