Abstract:
1. A method for forming a compound represented by Ar—Ar′, comprising the step of: combining a compound represented by ArX, a compound represented by Ax′B(OH) Ar and Ar′ are independently selected from the group consisting of optionally substituted monocyclic and polycyclic aromatic and heteroaromatic moieties; X is selected from the group consisting of Cl, Br, I, —OS(O) the transition metal is selected from the group consisting of the Group VIIIA metals; the ligand is selected from the group consisting of a compound represented by 2: wherein Q represent P(R) Y represents H, alkyl, N(R) R, R R m is independently for each occurrence an integer in the range 0 to 8 inclusive; and the ligand, when chiral, may be provided in the form of a mixture of enantiomers or as a single enantiomer; and the base is selected from the group consisting of carbonates, phosphates, fluorides, alkoxides, amides, carbanions, and silyl anions.
