An active bifunctional nickel catalyst was prepared by decomposing Ni(CO)4 to highly dispersed metallic Ni onto Hβ zeolite and first applied in hydroconverting benzyloxybenzene (BOB), which was used as a lignin-related model compound. Ni/Hβ proved to be effective for converting BOB to bicyclic cyclanes (BCCs) via Calk–O bond cleavage induced by H+ addition, benzylium addition to 2- and 4-positions in phenol, hydrogenation of benzene ring, dehydration, and H? abstraction. Compared to one-step conversion, the total BCC selectivity (TBCCS) significantly increases from catalytic hydroconversion of catalytically converted BOB by pretreatment under pressurized N2.

We report a C?F reductive elimination from a characterized first-row aryl metal fluoride complex. Reductive elimination from the presented nickel(III) complexes is faster than C?F bond formation from any other characterized aryl metal fluoride complex.

Amazing the crowd: A highly dispersive supported nickel catalyst is prepared by in situ decomposition of Ni(CO)4 over ZSM-5 zeolite. The catalyst displays an amazing activity for complete hydrogenation of polymethylbenzenes which are extremely
Nickel(0) complexes of polyunsaturated azamacrocyclic ligands
Brun, Sandra,Pla-Quintana, Anna,Roglans, Anna,Poerschke, Klaus-Richard,Goddard, Richard
, p. 1983 - 1990 (2012/04/23)
A series of nickel(0) complexes, 3, 4, and 5, containing unsaturated 15-membered azamacrocyclic ligands have been synthesized. Structural characterization of the complexes is based on NMR spectroscopy, X-ray diffraction analysis, and differential scanning calorimetry. In addition, the catalytic activity of the complexes in the Suzuki-Miyaura cross-coupling of arylboronic acids and aryl halides has been tested.
Bimetallic nickel-cobalt hexacarbido carbonyl clusters [H 6-nNi22Co6C6(CO)36] n- (n = 3-6) possessing polyhydride nature and their base-induced degradation to the monoacetylide [Ni9CoC2(CO) 16- x]3- (x = 0, 1)

, p. 4593 - 4600 (2012/07/14)
The reaction of [Ni10C2(CO)16] 2- with Co3(μ3-CCl)(CO)9 results in the new bimetallic Ni-Co hexacarbido carbonyl clusters [H 6-nNi22Co6C6(CO)36] n- (n = 3-6), which possess polyhydride nature and can be interconverted by means of acid-base reactions. The tetra-anion [H 2Ni22Co6C6(CO)36] 4- and the hexa-anion [Ni22Co6C 6(CO)36]6- have been isolated in a crystalline state and structurally characterized via X-ray crystallography. The six carbide atoms are lodged into Ni7CoC square antiprismatic cages. Addition of strong bases to [Ni22Co6C6(CO) 36]6- affords mixtures of the monoacetylides [Ni 9CoC2(CO)16]3- and [Ni 9CoC2(CO)15]3-, which have been cocrystallized as [NEt4]3[Ni9CoC 2(CO)16-x] (x = 0.58-0.84) salts, displaying tightly bonded interstitial C2 units.
Intramolecular rearrangement of the imine-amide ligand within the nickel coordination sphere affected by carbon monoxide
Kraikivskii, Peter B.,Klein, Hans-Friedrich,Saraev, Vitaly V.,Schl?rer, Nils E.,Bocharova, Victoria V.
, p. 3376 - 3383 (2011/10/09)
The interactions of the nickel imine-amide allyl complex 1 with carbon monoxide and unsaturated hydrocarbons have been studied. It is shown that this complex reacts readily with carbon monoxide to form the nickel(0) diimine carbonyl complex [(2-(1-propenyl)-[1,10]phenanthroline)Ni(CO)2] 2. During the process the ligand undergoes a deep transformation within the nickel coordination sphere. Specifically, the nickel-nitrogen σ-bond turns to an N-donor bond with aromatization of a ring in the nitrogen-containing ligand. This novel heteroaromatic ligand 2-(1-propenyl)-[1,10]phenanthroline has been isolated; the nickel(0) diimine carbonyl complex 2 has been studied with X-ray diffraction method. The comparative spectral studies of complexes 1, 2, and 2-(1-propenyl)-[1,10]phenanthroline have been carried out with UV/vis, IR-FT, and 2D NMR spectroscopy. It has been shown that the planar 16-electron nickel(II) imine-amide allyl complex 1 is indifferent to olefins and acetylenes. Based on the NMR data, this fact can be explained by the inability of the π-δ rearrangement into 1.
