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.

Dearomative syn-Dihydroxylation of Naphthalenes with a Biomimetic Iron Catalyst

open access: yesJournal of the American Chemical Society, 2023
Arenes are interesting feedstocks for organic synthesis because of their natural abundance. However, the stability conferred by aromaticity severely limits their reactivity, mostly to reactions where aromaticity is retained.

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 ...

Regioselective C-H Functionalization of Naphthalenes: Reactivity and Mechanistic Insights.

open access: yesChemPlusChem, 2020
Naphthalene is a very important skeleton in chemistry as evidenced by the large number of active compounds that contain it. For this reason, methods that can achieve easy functionalization of naphthalene derivatives are of great importance.

Mono- and Dinitro-BN-Naphthalenes: Formation and Characterization

open access: yesMolecules, 2021
Mono- and dinitro-BN-naphthalenes, i.e., 1-nitro-, 3-nitro-, 1,6-dinitro-, 3,6-dinitro-, and 1,8-dinitro-BNN, were generated in the nitration of 9,10-BN-naphthalene (BNN), a boron–nitrogen (BN) bond-embedded naphthalene, with AcONO2 and NO2BF4 in ...
