C¢H Bond Cyclometalation
Oxidation of zero-valent phosphine complexes [M(PBu3)2] (M=Pd, Pt) has been investigated in 1,2difluorobenzene solution using cyclic voltammetry and subsequently using the ferrocenium cation as a chemical redox agent. In the case of palladium, a mononuclear paramagnetic Pd derivative was readily isolated from solution and fully characterized (EPR, X-ray crystallography). While in situ electroch...
متن کاملRegioselective electrophilic borylation of haloarenes.
Haloarenes undergo direct borylation using amine : BCl3 : AlCl3 in the ratio of 1 : 1 : 2. After esterification the pinacol boronate esters are isolated in good yield with regioselectivity controlled by steric and electronic effects.
متن کاملEffect of ligand steric properties and halide identity on the mechanism for oxidative addition of haloarenes to trialkylphosphine Pd(0) complexes.
The oxidative addition of PhX (X = I, Br, Cl) to the complexes Pd(P(t)Bu(3))(2) (1), Pd(1-AdP(t)Bu(2))(2) (2), Pd(CyP(t)Bu(2))(2) (3), and Pd(PCy(3))(2) (4) (1-Ad = 1-adamantyl, Cy = cyclohexyl) was studied to determine the effect of steric properties on the coordination number of the species that undergoes oxidative addition and to determine whether the type of halide affects the identity of t...
متن کاملCooperative bimetallic oxidative addition reactions*
The factors that control the oxidation of metals in bimetallic complexes are investigated in relation to the possibility of developing one-site addition two-metal oxidation reactions such as those that occur in the respiratory protein, hemerythrin. It is shown that the behavior of bimetallic complexes is not represented by the sum of the analogous monometallic parts because of metal and ligand ...
متن کاملOxidative addition of ether O-methyl bonds at a Pt(0) centre.
Pt(PCyp3)2 (Cyp = cyclopentyl) undergoes C-O oxidative addition with 2,3,5,6-tetrafluoro-4-methoxypyridine, pentafluoroanisole, 2,3,5,6-tetrafluoroanisole and 2,3,6-trifluoroanisole yielding platinum methyl derivatives. The reactions occur in preference to C-H or C-F activation.
