Cationic Palladium η3-Allyl Complexes with Hemilabile P,O-Ligands : Synthesis and Reactivity : Insertion of Ethylene into the Pd-Allyl Function
Cationic palladium allyl complexes [(η3-C3H5)Pd(κ2P∧O)]+SbF6(2[SbF6], P∧O≡ Ph2P(CH2)2C(dO)OEt; 3[SbF6], o-Ph2PC6H4C(dO)OEt; 4[SbF6], Ph2P(CH2)2P(dO)Ph2) have been prepared. In all complexes the oxygen donor can be displaced by other ligands such as carbon monoxide and ethylene. Displacement of an ester donor occurs much more readily than displacement of the phosphine oxide function. Above 0 °C,...
متن کاملMetal-Metal Bonding in Uranium-Group 10 Complexes.
Heterobimetallic complexes containing short uranium-group 10 metal bonds have been prepared from monometallic IU(IV)(OAr(P)-κ(2)O,P)3 (2) {[Ar(P)O](-) = 2-tert-butyl-4-methyl-6-(diphenylphosphino)phenolate}. The U-M bond in IU(IV)(μ-OAr(P)-1κ(1)O,2κ(1)P)3M(0), M = Ni (3-Ni), Pd (3-Pd), and Pt (3-Pt), has been investigated by experimental and DFT computational methods. Comparisons of 3-Ni with t...
متن کاملInterplay of metal-allyl and metal-metal bonding in dimolybdenum allyl complexes.
Addition of PMe3 to Mo2(allyl)4 afforded Mo2(allyl)4(PMe3)2, in which two of the allyl groups adopt an unprecedented micro2-eta1,eta3 bonding mode; theoretical studies elucidate the roles of the sigma- and pi-donor ligands in the interplay of metal-allyl and metal-metal bonding.
متن کاملIntercalation of a molybdenum η3-allyl dicarbonyl complex in a layered double hydroxide and catalytic performance in olefin epoxidation.
A Zn-Al layered double hydroxide (LDH) intercalated by [Mo(η(3)-C3H5)Cl(CO)2(bpdc)](2-) anions (bpdc = 2,2'-bipyridine-5,5'-dicarboxylate) has been prepared by coprecipitation from aqueous solution and characterised by various techniques. The one-pot method gives rise to a highly organised intercalate with an interlayer spacing of 18.3 Å and up to six (00l) basal reflections in the powder X-ray...
متن کاملOrigin of the allyl group in FK506 biosynthesis.
FK506 (tacrolimus) is a secondary metabolite with a potent immunosuppressive activity, currently registered for use as immunosuppressant after organ transplantation. FK506 and FK520 are biogenetically related natural products that are synthesized by combined polyketide synthase/nonribosomal peptide synthetase systems. The entire gene cluster for biosynthesis of FK520 from Streptomyces hygroscop...
