PCNP diphosphines, in conjunction with Cr(acac)3, are excellent ethylene oligomerisation catalysts high activity and selectivity towards both 1-hexene 1-octene formation.

In the title compound, C31H30N2O, the cis-fused cyclo-hexene and cyclo-octane rings adopt boat and boat-chair conformations, respectively. The essentially planar five-membered N-heterocyclic ring [r.m.s. deviation = 0.017 (1) Å] is cis- and trans-fused, respectively, with the cyclo-hexene and cyclo-octane rings. In the crystal, mol-ecules are linked into inversion dimers through pairs of weak C...

The one-pot synthesis of butanol and heptanol from propene and 1-hexene, respectively, was performed using Ru3(PPh3)Cl2 and Rh(CO)2(acac) in the presence of triphenylphosphene. The effects of various reaction parameters, including catalyst concentration, gas partial pressures, and temperature, were investigated. Two methods for performing the one-pot synthesis were developed and are discussed. ...

1-Pentene, respectively 1-hexene, were reacted with 13 homogeneous metallocene catalysts to give linear oligomerization products, predominantly dimers, with selectivities above 90%. The product distributions of the codimerization reactions of 1-pentene with 1-hexene reflected a binomial behaviour. Therefore, the ratio for dimers is 1:2:1 (C10:C11:C12) while the trimers (pentadecenes up to octad...

Nine different bis(arylimino)pyridine complexes of Fe(III) with different halide substituents (F, Cl, Br, I) at different positions of the iminophenyl group of the ligand have been synthesized, characterized and applied for homogeneous 1-pentene and 1-hexene oligomerization and co-oligomerization reactions after activation with methylaluminoxane (MAO). The best activity in 1-hexene oligomerizat...
