Page/Page column 15, (2010/08/07)
Organozinc compounds of the type R1—Ar1—ZnY (1) can be reacted with different functionalized aryl halides R2—Ar2—X (2) in the presence of catalytic amounts of Ni or Fe in a polar solvent or solvent mixture to form polyfunctional biaryles of the type R1—Ar1—Ar2—R2 (3). Organozinc compounds of the type (1) can be represented by the transmetallation reaction of functionalized aryl magnesium halides or lithium aryl compounds with e.g. ZnBr2.
