The cyclo-hexene ring in the title compound, C(15)H(18)INO(2), adopts a sofa conformation. The dihedral angle between the cyclo-hexene (through all ring atoms) and benzene rings is 63.3 (1)°. The mol-ecular conformation features an N-H⋯I short contact and the crystal packing features C-H⋯O hydrogen bonds.

The title compound, C(12)H(12)Cl(2)O(2), has a bicyclic skeleton containing cyclo-hexene and benzene fragments. The cyclo-hexene ring adopts a half-chair conformation with displacements of two atoms out of the least-squares plane of 0.311 (2) and -0.336 (2) Å. The Cl atoms are trans-positioned.

A structurally well-defined THF-free cationic half-sandwich scandium aminobenzyl complex serves as a novel catalyst for the first copolymerization of 1-hexene with dicyclopentadiene to give the random copolymers with a wide range of 1-hexene contents (32-70 mol%) unavailable previously.

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 highly conjugated title compound, C(23)H(25)Cl(2)N(3), is nearly planar (the mean deviation from the plane being 0.049 Å), except for the -C(CH(3))(2) group on the cyclo-hexene ring and the two CH(2)Cl groups. The cyclo-hexene ring has an envelope configuration. In the crystal, the packing is stabilized by C-H⋯Cl inter-actions and C-H⋯π inter-actions involving the benzene ring.

The new highly active supported vanadium-magnesium catalyst (VMC) has been studied in α-olefin (1-butene, 1-hexene)/ ethylene copolymerization in the presence of hydrogen. Data on the effect of α-olefin/ethylene ratio in copolymerization on the content of branchings in copolymers, kinetic profile, copolymer yield, molecular weight and molecular weight distribution of copolymers have been obtain...

Five new iron(III) 1-hexene polymerisation catalysts were prepared from the reactions of 2,4-di-tert-butyl-6-(2-(1H-imidazol-4-yl)ethylimino)methylphenol (L1), or 4-tert-butyl-6-(2-(1Himidazol-4-yl)ethylimino)methylphenol (L2) or 2,4-di-tert-butyl-6-[(2-pyridin-2-yl-ethylimino)methyl-phenol (L3) with anhydrous iron(II) halides to form [FeCl2(L1)] (1), [FeBr2(L1)] (2), [FeI2(L1)] (3), [FeBr2(L2)...

The title compound, C(21)H(22)O(5), was prepared by NaOH-catalysed cyclo-condensation of 3-(4-ethoxy-phen-yl)-1-(furan-2-yl)prop-2-en-1-one with ethyl acetoacetate. In the crystal, C-H⋯O and C-H⋯π inter-actions link the mol-ecules. In the title mol-ecule, the furan and cyclo-hexene rings are almost parallel [6.77 (11)°] and the cyclo-hexene ring is approximately perpendicular to the benzene rin...

The Lewis acid-catalyzed domino 1,2-addition/1,4-addition/elimination between (Z)-3-hexene-2,5-dione and 1,3-dicarbonyls delivers 3-methyl-6,7-dihydrobenzofuran-4(5H)-ones exclusively with yields up to 82%. The combination of this new process with the laccase-catalyzed formation of (Z)-3-hexene-2,5-dione by oxidative cleavage of 2,5-dimethylfuran allows for the synthesis of 6,7-dihydrobenzofura...

Propene-hexene copolymers crystallize in a new polymorphic form of isotactic polypropylene when the concentration of hexene is higher than nearly 10-15 mol %. The hexene units are included in the crystals, inducing an increase of density that allows crystallization of 3-fold helical chains in a trigonal unit cell according to the space group R3c or Rc, where the helical symmetry of the chains i...
