China refined naphthalene market: New market research published

In this work, the racemate and mesomer of the thiophene-based naphthalene-cored double helicenes (1) were obtained efficiently by one-pot photocyclization of 1,1,2,2-tetrakis(dithieno[2,3-b:3′,2′-d]thiophen-2-yl)ethene in the presence of iodine ...

Anti-1,8-bisTPI-naphthalene in which two imidazole rings are constrained to an anti-conformation leading to the first-formed 1,4′-isomer of the bridged imidazole dimer has been synthesized. The color of the radicals is different from that of the ...

DFT calculations have been performed on the naphthalene cationic complex η6-C10H8RuCp+ in the presence of different anions. In a first step, geometry optimization of the PF6 salt carried out in the presence of 15 solvent molecules for 3 different ...

A facile one-pot synthetic route for preparing the novel benzofused tricyclic skeleton of 1,2,2a,8b-tetrahydrocyclobuta[a]naphthalenes 5 is developed. The route was realized by a NaH-mediated tandem aldol condensation/olefin ...

The enzymatic dearomatization of aromatic ring systems by reduction represents a highly challenging redox reaction in biology and plays a key role in the degradation of aromatic compounds under anoxic conditions. In anaerobic bacteria, most ...

The highly affinitive and selective binding processes of tetrasulfonated 1,5-dinaphtho-38-crown-10 (14) and tetrasulfonated 1,5-dinaphtho-32-crown-8 (24) with pyromellitic diimide and naphthalene diimide derivatives bearing cationic terminal groups ...

A PPh2- and BMes2-functionalized (Mes = mesityl) 1,8-naphthalene molecule (1) has been synthesized and fully characterized. Compound 1 is a highly congested molecule with a PB dative bond. NMR studies support that the PB bond in 1 is persistent in ...

Mbandakamines A (1) and B (2), isolated from the leaves of an as yet unidentified Congolese Ancistrocladus species, are the first dimeric naphthylisoquinoline alkaloids with an unsymmetrically coupled central biaryl axis. Their novel ...

Highly enantiopure (1-aryl)- and (1-naphthyl)-1-ethylamines were synthesized by the borane-mediated reduction of single-isomeric (E)- and (Z)-O-benzyloxime ethers using the stable spiroborate ester derived from (S)-diphenyl valinol and ethylene ...
