The relative importance of the factors contributing to the accelerating effect of CuI on [PdL4]-catalyzed couplings of R1I and R2SnBu3 (copper effect) has been quantitatively evaluated in THF for R1 = 3,5-C6Cl2F3; R2 = vinyl, C6H4-4-OMe; L = AsPh3, P

The zirconium dimethyl complexes [N2NX]ZrMe2 (N2NX = [(MesNCH2CH2)2NX]; Mes = mesityl; X = H (1a), Me (1b)), have “mer” structures in the solid state in which the amido nitrogens occupy “axial” positions in a trigonal bipyramid. The reaction

Interconversion of the syn and anti rotational isomers of cis-[Pd(2-C6BrF4)2(tht)2] (1) (tht = tetrahydrothiophene) takes place very fast in CDCl3 solution. The process has been studied by 19F NMR magnetization transfer experiments. The first-order s

The so far accepted mechanism of the Stille reaction (palladium-catalyzed cross-coupling of organotin reagents with organic electrophiles) is criticized. Based on kinetic studies on catalytic reactions, and on reactions with isolated intermediates, a

[AuR1(tht)] (3a) (R1 = 3,5-C6Cl2F3, tht = tetrahydrothiophene) very efficiently catalyzes the isomerization of trans-[Pd(R1)2(tht)2] (1a) to cis-[Pd(R1)2(tht)2] in CDCl3. The 19F NMR kinetic study leads to the first-order rate law riso = kiso[1a] = (

Palladium(II) complexes with the asymmetric aryl groups o-C6BrF4 and m-C6BrF4 have been synthesized, namely [Pd2(C6BrF4)2(μ-Cl)2(tht)2], trans-[Pd(C6BrF4)Cl(tht)2] (tht = tetrahydrothiophene), trans-[Pd(C6BrF4)2L2], and cis-[Pd(C6BrF4)2L2] (L2 = 2th
