Five of the atoms of the six-membered cyclo-hexene ring of the title compound, C(17)H(20)O(2), are essentially coplanar (r.m.s. deviation = 0.006 Å), with the sixth (the dimethyl-methyl C atom) deviating from the mean plane of the five atoms by 0.610 (2) Å. This plane is nearly perpendicular to the cinnamyl portion, the two planes being aligned at 85.1 (1)°. Two mol-ecules are linked by an O-H⋯...

In the title compound, C(17)H(17)NO(3)S, the cyclohexene ring is essentially planar, with a maximum deviation of 0.006 (1) Å. The cyclo-hexene ring adopts a half-chair conformation. The dihedral angle between the thio-phene and benzene rings is 29.7 (1)°. The mol-ecular structure exhibits intra-molecular O-H⋯O, O-H⋯N and C-H⋯S hydrogen bonds, which generate one S(5) and two S(6) motifs. There i...

A catalyst for the oligomerization of 1-hexene, generated by the activation of a benzimidazolylidene zirconium dibenzyl complex, switches to a polymerization catalyst on addition of a trialkylphosphine.

In the title compound, C(15)H(11)N(3), the cyclo-hexene ring adopts a sofa conformation. An intra-molecular N-H⋯N hydrogen bond generates an S(7) ring motif. In the crystal, mol-ecules are linked by inter-molecular N-H⋯N, C-H⋯N and C-H⋯π inter-actions into a three-dimensional network.

In the title compound, C(14)H(18)N(2)O(3)S, the cyclo-hexene ring exhibits a distorted half-chair conformation and its mean plane makes a dihedral angle of 46.18 (8)° with the benzene ring. In the crystal, mol-ecules are linked via N-H⋯O, N-H⋯(O,O) and C-H⋯O hydrogen bonds, forming a three-dimensional network.

In the title compound, C(20)H(32)N(2)O(2)S(2), the cyclo-hexene ring is disordered over two half-boat conformations with occupancy factors of 0.71:0.29. One n-butyl chain is also disordered over two positions with occupancy factors of 0.83:0.17. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond.

In the title crystal structure, C(10)H(16)O(2), inversion-related mol-ecules are linked by pairs of O-H⋯O hydrogen bonds involving carboxyl groups to form R(2) (2)(8) dimers. The cyclo-hexene ring displays a half-chair conformation.

The 3-cyclo-hexene units adopt envelope conformations in each of the two independent mol-ecules that comprise the asymmetric unit of the title compound, C(20)H(16)F(2)O(3). The dihedral angles between the two fluoro-phenyl rings are 79.7 (2) and 73.7 (2)° in the two mol-ecules. In one of the mol-ecules, two C-H groups of the cyclo-hexene ring are disordered over two sets of sites in a 0.818 (13...
