Copper-catalysed cross-coupling of arylzirconium reagents with aryl and heteroaryl iodides

An unprecedented CuI-catalysed cross-coupling of arylzirconium reagents with aryl and heteroaryl iodides is reported. Mechanistic studies with a Cp2ZrAr2 complex revealed that Cp2Zr(Ar)(Cl) is the reactive species that undergoes transmetalation with (PN-1)CuI. In addition, experiments with radical probes indicated that the reaction proceeds via a non-radical pathway. This journal is

Process for preparing 4'-trifluoromethyl-2-methylbiphenyl and 4'-trifluoromethyl-biphenyl-2-carboxylic acid from o-tolylmetallates

The invention relates to a process for preparing a compound of the formula (I) in which R is methyl or carboxyl, which comprises coupling an ortho-tolylmetallate of the formula (II) with a compound of the formula (III) in which M is —MgF, —MgCl, —MgBr, —Mgl, —Li, —ZnF, —ZnCl, —ZnBr or —Znl and X is F, Cl, Br, I, N2+, straight-chain or branched (C1-C20)-alkoxy, arylsulfonate or alkylsulfonate in the presence of an Ni, Pd or platinum metal catalyst to give a compound of the formula (I) where R is CH3 and, if appropriate, oxidizing the compound of the formula (I) where R is CH3 to give the compound of the formula (I) where R is carboxyl.
