The development of a germanium-based linker system for the solid phase synthesis (SPS) of 3-(n-hexyl)thiophene oligomers and the first SPS of triarylamine oligomers via iterative chain extension is described. The efficiency of the key steps in the oligomer syntheses and their compatibility with the germanium linker are demonstrated by the SPS of bi-[3-(n-hexyl)thiophene] 19 and ter-(triarylamin...

In the title compound, [Cu(C(16)H(11)BrN(2))(C(18)H(33)P)]BF(4), the Cu(I) atom is three-coordinated in a distorted trigonal configuration by two N atoms from the 6-(4-bromo-phen-yl)-2,2'-bipyridine ligand and a P atom from the tricyclo-hexyl-phosphine ligand. In addition, a weak anion⋯Cu(I) inter-action with a nearest F⋯Cu separation of 2.696 (5) Å is found.

The fluorescence of the dye CC-6 [(3-hexyl-2-(3-hexyl-2-benzoxazolinylidene)-1-propenyl)-benzoxazolium iodide] has been shown to indicate Donnan potentials in rabbit skeletal muscle myofibrils. These results are in agreement with previously published work in which the potentials were measured with microelectrodes on glycerol-extraced muscle fibers. The magnitude of the Donnan potential of the m...

In the title compound, C(25)H(34)O(4), one n-hexyl chain of the hex-yloxy group adopts a fully extended all-trans conformation, and the other n-hexyl chain displays disorder with site occupancies of 0.470 (3) and 0.530 (3). The dihedral angle between the benzene rings is 44.5 (3)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds form dimers via crystallographic inversion centres.

In the title asymmetric di-cyclo-hexyl-phenyl-guanidine, C25H41N3, the central guanidine C atom deviates by only 0.004 (2) Å from the central plane defined by the three N atoms. The benzene and the cyclo-hexyl rings are rotated out of the central plane of the N3C unit by 85.63 (12)° (benzene) and 51.52 (9) and 49.37 (12)° (cyclohexyl). The crystal packing features only by van der Waals inter-ac...

The title compound, C(19)H(31)O(2)P, features a distorted tetra-hedral P atom that bonds to the phenyl ring, isopropyl and 2-isopropyl-5-methyl-cyclo-hexyl groups, and is determined as having an R(p) configuration. A chair conformation is observed for the cyclo-hexyl ring. In the crystal, mol-ecules are linked into chains running along the a axis by weak inter-molecular C-H⋯O hodrogen bonds.

The title compound, C(31)H(38)N(2), was prepared from bis-(4-amino-cyclo-hexyl)methane and two equivalents of cinnamaldehyde. The cyclo-hexyl groups each show a chair conformation and the α,β-unsaturated imine side chains are all-trans configured. Two mol-ecules of the title compound as well as two trichloromethane solvent mol-ecules are present in the asymmetric unit. The solvent mol-ecules in...

Hexyl butyrate, a green note flavour compound, is widely used in the food industry. The ability of immobilised lipase (Lipozyme IM-77) from Rhizomucor miehei to catalyse the transesterification of hexanol and tributyrin was investigated in this study. Response surface methodology (RSM) and five-level-five-factor central composite rotatable design (CCRD) were employed to evaluate the effects of ...

The mol-ecule of the title compound, C(31)H(29)N(3), contains a hexyl chain, a coordination unit (benzimidazole) and a functional group (carbazole). The benzimidazole ring is not coplanar with either the phenyl ring or the carbazole system, making dihedral angles of 43.26 (3) and 39.03 (2)°, respectively. The dihedral angle between the phenyl ring and the carbazole system is 24.42 (3)°. The hex...
