Abstract
The efficient synthesis of sterically demanding tetra-substituted biaryls by means of a one-pot three steplow-temperature modification of the classical Ullmann reaction is reported. The major benefit of this methodology lies in the ready synthesis of polybrominated biaryls, which can be subsequently functionalizedinto various target molecules by means of regioselective halogen/metal permutations.
