Direct Synthesis of Substituted Naphthalenes from 1,3-Dicarbonyl Compounds and 1,2-Bis(halomethyl)benzenes Including a Novel Rearrangement Aromatization of Benzo[c]oxepine

open access: yes, 2016
An unexpected rearrangement aromatization of benzo[c]oxepine has been revealed to synthesize substituted naphthalenes. This observation was further exploited to develop an efficient approach for the construction of naphthalenes from simple and ...

Stereoselective [4+2] Cycloaddition of Singlet Oxygen to Naphthalenes Controlled by Carbohydrates

open access: yesMolecules, 2021
Stereoselective reactions of singlet oxygen are of current interest. Since enantioselective photooxygenations have not been realized efficiently, auxiliary control is an attractive alternative.

Perfluorohalogenated Naphthalenes: Synthesis, Crystal Structure, and Intermolecular Interaction [PDF]

open access: yes, 2023
Perfluorohalogenated naphthalenes (PFXNaPs) are unique small molecules with great potential to exhibit a new type of σ-hole and π-hole bonding, owing to the incorporation of multiple fluorine atoms onto the naphthalene ring.

Spirodienone and Bis(spirodienone) Derivatives of Calix[4]naphthalenes

open access: yes, 2016
Calix[4]naphthalenes 11 and 12 in which hydroxyl groups are situated intraannularly can be oxidized with PTMATB and base to form the bis(spirodienone) 13, from 11, and bis(spirodienone) 20−21 and spirodienone 22, from 12.

Function of aromatic compounds as indicators in laboratory experiments of heavy oil with fire flooding

open access: yesShiyou shiyan dizhi, 2022
Identifying whether high-temperature oxidation is realized in fire flooding has become one of the technical difficulties in evaluating the effect of fire flooding for heavy oil reservoirs. In order to study how the chemical properties of crude oil varied

Naphthalenes and Quinolines by Domino Reactions of Morita–Baylis–Hillman Acetates

open access: yesMolecules, 2020
An efficient synthetic route to highly functionalized naphthalenes and quinolines has been developed using domino reactions between Morita–Baylis–Hillman (MBH) acetates and active methylene compounds (AMCs) promoted by anhydrous K2CO3 in dry N,N ...
