PLATIN-KOHLENSTOFF-?-BINDUNGEN MIT GEHINDERTER ROTATION: 4-BICYCLOHEPTA-2,5-DIEN>-(E)-BIS(2-ETHOXYNAPHTH-1-YL)PLATIN(II)
Weisemann, Claus,Brune, Hans Albert
, p. 133 - 138 (1986)
The synthesis of 4-bicyclohepta-2,5-diene>-(E)-bis(2-ethoxy-naphth-1-yl)platinum(II) has been described.As a consequence of the two adjacent naphthalene rings the compound has a stationary E-conformation; there is no rotation about the platinum-carbon ?-bonds.

Atropisomeric (hetero)biaryls are motifs with increasing significance in ligands, natural products, and biologically active molecules. The straightforward construction of the stereogenic axis by efficient C-H functionalization methods is extremely rare an
Aerobic oxidative bromination of arenes using an ionic liquid as both the catalyst and the solvent

A method for the bromination of alkoxy-substituted benzenes and naphthalenes was developed by using the residual oxygen in the reaction tube as the oxidant, and [Bmim]NO3 (1-butyl-3-methylimidazolium nitrate) ionic liquid as both the catalyst and the solvent. No other reagent apart from the ionic liquid and molecular bromine was used in the reactions, and basically all the bromine atoms in the bromine source were transferred to the bromination products, showing that the presented protocol is highly atom economic and practical.
Cetyltrimethylammonium bromide as an efficient catalyst for regioselective bromination of alkoxy naphthalenes with trimethyl benzyl ammonium tribromide: Synthetic and kinetic approach
Reddy, K. Rajendar,Rajanna,Uppalaiah,Ramgopal
, p. 10 - 23 (2014/01/06)
Bromination of 2-alkoxynaphthalene (2-ANP) and its derivatives with trimethyl benzyl ammonium tribromide (TMBATB) did not proceed smoothly even under reflux conditions. But the addition of microconcentrations of cetyltrimethyl ammonium bromide (CTAB) to t
Highly selective insertion of arynes into a C(sp)-O(sp3) σ Bond

Arynes react with ethoxyacetylene to afford 2-ethoxyethynylaryl derivatives through a highly chemo-and regioselective formal insertion of the aryne into the C(sp)-O(sp3) bond of the alkyne. Computational studies suggest that the reaction does n
Sodium nitrite-catalyzed oxybromination of aromatic compounds and aryl ketones with a combination of hydrobromic acid and molecular oxygen under mild conditions
Zhang, Guofu,Liu, Renhua,Xu, Qing,Ma, Lixin,Liang, Xinmiao

A novel and efficient catalytic system for the oxybromination of aromatic compounds and aryl ketones utilizing a combination of aqueous hydrobromic acid and molecular oxygen in the presence of sodium nitrite under mild conditions has been developed. The newly developed catalytic system utilizes cheap and readily available reactants, exhibits high bromine atom economy and releases only innocuous water as the by-product.
Regioselective Halogenation and Dimerization of Alkoxynaphathalenes with Alumina- or Kieselguhr-supported Copper(II) Halides
Suzuki, Yoshitada,Takeuchi, Kiyoshi,Kodomari, Mitsuo
, p. 426 - 427 (2007/10/03)
The reaction of 1-alkoxynaphathalenes 1 with alumina-supported copper(II) bromide or copper(II) chloride gave dimers, 4,4'-dialkoxy-1,1'-binaphthyls 3, as major products, and with Kieselguhr-supported copper(II) bromide afforded 1-bromo-4-alkoxynaphthalenes 2, while the reaction of 2-alkoxynaphathalenes 4 with alumina- or Kieselguhr-supported copper(II) bromide gave preferentially 1-bromo-2-alkoxynaphthalenes 5.
