Reaction of Pd(acac)2 with 1 equiv of the lithium beta-diketiminate Li(iPr2-nacnac) (iPr 2-nacnac = CH{C(Me)NiPr}2) affords the dark red mixed-ligand complex (acac)Pd(iPr2-nacnac) (1), while with 2 equiv of Li(iPr2-nacnac) the light red homoleptic Pd(iPr2-nacnac)2 (2) is formed. A similar reaction of Pd(acac)2 with the more bulky (THF)Li(Ar 2-nacnac) (Ar2-nacnac = CH{C(Me)N(C6H 3-2,6-iPr2)}2) proceeds only to the stage of the mixed-ligand complex. While below 0 C red (acac) Pd(kappa2N,N-Ar2-nacnac) (4) is isolated as the kinetically controlled product, which is stable in the solid state, this complex isomerizes in solution at ambient temperature to yield the lighter red and chiral (acac)Pd(kappa2C,N-Ar2-nacnac) (5), displaying a novel nacnac bonding mode. The reaction of [Pd(MeCN)4](BF 4)2 and that of the Pd(I) complex [Pd2(MeCN) 6](BF4)2 with (THF)Li(Ar2-nacnac) gives [kappa2N,N-Ar2-nacnac)Pd(MeCN)2]- (BF4) (6). The kappa2N,N-Ar2-nacnac ligand in 6 is sufficiently nucleophilic to displace acetonitrile from [Pd(MeCN) 4](BF4)2 and produce the pure dinuclear [(MeCN)3Pd{mu-CH(C(Me)NAr)2}Pd(MeCN)2] (BF4)3 (A), previously accessible only in a mixture. From the reactions of {(eta3-C3H5)Pd(mu-Cl)} 2 with Li(iPr2-nacnac) and (THF)Li(Ar 2-nacnac) the mixed-ligand complexes (eta3-C 3H5)Pd(iPr2-nacnac) (3a) and (eta3-C3H5)Pd(kappa2N,N-Ar 2-nacnac) (3b) have been obtained. Reaction of (cod)PdMeCl with (THF)Li(Ar2-nacnac) affords (Ar2-nacnac)PdMe(MeCN) (7). An anisotropic effect of the Ar2-nacnac ligand in the 1H NMR spectra of 3b and 4 can be noted. The structures of 2, 3a, 4, and 5 have been determined by X-ray crystallography.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 21797-13-7
