Nickel acetylacetonate chloride

Examples of w-allylnickel-X compounds (X = anionic ligand) other than 77-allylnickel halides which have been used in combination with (alkyl)aluminum halides as olefin oligomerization catalysts are 7r-allyl-nickel acetylacetonate (11) (Section III), 7r-allylnickel aziridide (4, 56), and bis(7r-allyl)nickel (6) (59). In addition to ir-allylnickel halides, organo-nickel halides such as tritylnickel chloride (60, 61) and pentafluoro-phenylbis(triphenylphosphine)nickel bromide (62), or hydridonickel halides, e.g., trans-hydridobis(triisopropylphosphine)nickel chloride (12) (Section III), give active catalysts after activation with aluminum halides...

An alternative procedure starts from a metal complex of o-phenylenedi-amine. For example, the bis(o-phenylenediamine) complex of nickel(II) chloride reacts with acetylacetone to give a mixture of a nickel complex of the diamine and diketone together with 2,4-dimethylbenzodiazepinium chloride (76CPB1934 91JPR327). Chromium complexes have been used in the same way [91JCS(D)2045].

The crosslinked graft-copolymers were contacted with hydrocarbon solvent (n-heptane, toluene) and in the swollen form they were treated with salts of nickel (nickel chloride, nickel acetylacetonate), titanium (dibutoxytitanium dichloride) or zirconium (dibutoxyzirconium dichloride). 

Treatment of buca-l,3-diene with titaniumfiv) chloride and diethylaluminium chloride gave a mixture of cis,rrans,rran cyclododeca-l,5,9-triene and all-trons-cyclohexadeca-l,5,9,13-tetraene. The co-dimerization of buta-1,3-diene and iso-prene or trons-1-piperylene by nickel acetylacetonate in the presence of triphenyl-phosphite and perhydro-9b-alumophenalene to give 1- or 3-methylcyclo-octa-1,5-diene, has been studied. Buta-1,3-diene has been cyclo-oligomerized in the presence of a nickel catalyst to give a mixture all-rrans-cyclododeca-l,5,9-triene, all trans-cyclohexadeca-1,5,9,13-tetraene and 11-vinyl-all-trans-cyclotetradeca-1,4,8-triene, in the ratio of 80 15 5, respectively, in 90% combined yield. The catalytic... 

The first attempts to synthesis asymmetric polyisocyanides are recent ones [30]. Asymmetric polymerization of racemic isocyanide (Xllla) with nickel chloride or nickel acetylacetonate catalyst was attempted in the presence of chiral solvents, (-)-borneol or (+)-sec-butyl-alcohol, or in the presence of (+)-nickel alaninate with the racemic a-phenyl-ethylisocyanide (Xlllb), but the polymers did not show any activity. 

Catalytic homogeneous hydrogenation of cyclohexene has been claimed for simple systems such as nickel(II) acetylacetonate [39] or a nickel-chloride complex with two monodentate amines [40]. The latter complex was used as comparison for a heterogeneous catalyst obtained by impregnation of the complex on y-alu-mina [40]. SCRs of 100 were used at 30 atm. H2 and temperatures up to 100°C, resulting in conversions of only 20-35% after 1 h.
