Aryl-aryl bond formation one century after the discovery of the Ullmann reaction.

The biaryl structural motif is a predominant feature in many pharmaceutically relevant and biologically active compounds. As a result, for over a century 1 organic chemists have sought to develop new and more efficient aryl -aryl bond-forming methods. Although there exist a variety of routes for the construction of aryl -aryl bonds, arguably the most common method is through the use of transition-metalmediated reactions. 2-4 While earlier reports focused on the use of stoichiometric quantities of a transition metal to carry out the desired transformation, modern methods of transitionmetal-catalyzed aryl -aryl coupling have focused on the development of high-yielding reactions achieved with excellent selectivity and high functional group tolerance under mild reaction conditions. Typically, these reactions involve either the coupling of an aryl halide or pseudohalide with an organometallic reagent (Scheme 1), or the homocoupling of two aryl halides or two organometallic reagents. Although a number of improvements have developed the former process into an industrially very useful and attractive method for the construction of aryl -aryl bonds, the need still exists for more efficient routes whereby the same outcome is accomplished, but with reduced waste and in fewer steps. In particular, the obligation to use coupling partners that are both activated is wasteful since it necessitates the installation and then subsequent disposal of stoichiometric activating agents. Furthermore, preparation of preactivated aryl substrates often requires several steps, which in itself can be a time-consuming and economically inefficient process.

N-Heterocyclic Carbenes in Late Transition Metal Catalysis

The highly constrained, axially chiral atropos diamines (Ri,S,S)-1, (Ri,R,R)-1 and (Ri,S,R)-1 and their tropos analogue (Ri)-2 have been prepared via bis-N,N-dialkylation of (R)-2,2′-diamino-1,1′-binaphthyl, using either (R)- or (S)-2,2′-bis(bromomethyl)-1,1′-binaphthyl and 2,2′-bis(bromomethyl)-1,1′-biphenyl as alkylating agents, followed by selective nickel chloride-catalysed bis(mono-hydrogenolysis) of the tertiary amino groups of the so-obtained (Ri,R,R)-4, (Ri,S,S)-4, (Ri,R,S)-4 and (Ri)-6, respectively, by lithium aluminium hydride in refluxing THF or THF/diglyme. The diamines (Ri,S,S)-1, (Ri,R,R)-1, (Ri,S,R)-1 and (Ri)-2 have been evaluated as ligands for ytterbium-catalysed intramolecular hydroamination and compared to the ligand 1,1′-binaphthyl-2,2′-bis(benzylamine) (Ri)-3. They afforded highly active catalysts for the cyclisation of aminopentenes and aminohexenes with up to 58% ee.
