In the title compound, C(15)H(10)ClFO(2)S, the O atom and the methyl group of the methyl-sulfinyl substituent are located on opposite sides of the plane through the benzofuran fragment. The 4-chloro-phenyl ring is rotated out of the benzofuran plane, as indicated by the dihedral angle of 21.04 (4)°. The crystal structure exhibits a weak inter-molecular C-H⋯O hydrogen bond and a Cl⋯O halogen bon...

In the title compound, C24H18Cl2N2O5, the quinoline and quinolinone moieties are nearly perpendicular to each other, forming a dihedral angle of 82.36 (3)°. In the crystal, mol-ecules form a halogen bond between a Cl atom of a quinolinone moiety and the N atom of the quinoline moiety of the inversion equivalent [Cl⋯N = 3.106 (3) Å]. The mol-ecules also form two kinds of C-H⋯O hydrogen-bonded ce...

The synthesis of an all-halogen-bonding rotaxane for anion recognition is achieved by using active-metal templation. A flexible bis-iodotriazole-containing macrocycle is exploited for the metal-directed rotaxane synthesis. Endotopic binding of a Cu(I) template facilitates an active-metal CuAAC iodotriazole axle formation reaction that captures the interlocked rotaxane product. Following copper-...

The role of the closing lecture in a Faraday Discussion is to summarise the contributions made to the Discussion over the course of the meeting and in so doing capture the main themes that have arisen. This article is based upon my Closing Remarks Lecture at the 203rd Faraday Discussion meeting on Halogen Bonding in Supramolecular and Solid State Chemistry, held in Ottawa, Canada, on 10-12th Ju...

Benchmark quality structures and interaction energies have been produced using explicitly correlated coupled cluster methods for a systematic series of hydrogen and halogen bonded complexes: B···HCCH, B···HCl and B···ClF, with six different Lewis bases B. Excellent agreement with experimental structures is observed, verifying the method used to deduce the equilibrium deviation from collinearity...

Tetryzoline(TH) is an adrenergic agent (vasoconstrictors) and derived from imidazoline. This compound is closely related to naphazoline hydrochloride in its pharmacological action. Nanotechnology has been used to provide advanced biomedical research tools in drug delivery. The fullerene family especially C60 derivatives have appealing photo-, electro-chemical and physical properties for biomedi...

The title nitro-phenyl benzamide, C13H9BrN2O3, with two mol-ecules in the asymmetric unit, has dihedral angles of 16.78 (15) and 18.87 (14)° between the benzene rings. An intra-molecular N-H⋯O hydrogen bond is observed in each mol-ecule. In the crystal, the molecules are linked by weak C-H⋯O inter-actions; halogen-halogen inter-actions are also observed [Br⋯Br = 3.4976 (7) Å]. These inter-actio...

The Wittig reaction of perfluorohalobenzaldehydes was systematically studied to synthesize 2,3,5,6-tetrafluoro-4-halostyrene (TFXS) as functional monomers bearing halogen bond donor sites. proceeded efficiently in tetrahydrofuran using 1,1,3,3-tetramethylguanidine the organic base. Correlation analysis quantitatively identified three key factors required obtain TFXS reasonable yields. present a...

Self-assembly of block copolymers into well-defined, ordered arrangements of chemically distinct domains is a reliable strategy for preparing tailored nanostructures. Microphase separation results from the system, minimizing repulsive interactions between dissimilar blocks and maximizing attractive interactions between similar blocks. Supramolecular methods have also achieved this separation by...
