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 ...
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 ...
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 ...
