Development and optimization of analytical methods for the detection of 18 taste and odor compounds in drinking water utilities

open access: yesWater Research X, 2021
Taste and odor (T&O) issues have been a major concern among drinking water utilities as source waters are becoming increasingly vulnerable to compounds released during algal blooms as well as non-algal compounds.

Sources and pathways of halomethoxybenzenes in northern Baltic estuaries

open access: yesFrontiers in Marine Science, 2023
IntroductionThousands of halogenated natural products (HNPs) are generated in the ocean and on land. A subset of these, halomethoxybenzenes (HMBs), are released from both natural and anthropogenic sources. Here we consider: 1.

Electrocatalyzed direct arene alkenylations without directing groups for selective late-stage drug diversification

open access: yesNature Communications, 2023
Electrooxidation has emerged as an increasingly viable platform in molecular syntheses that can avoid stoichiometric chemical redox agents. Despite major progress in electrochemical C−H activations, these arene functionalizations generally require ...

Experimental and Theoretical Studies on the Corrosion Inhibition Potentials of some Anisole derivatives for Mild Steel

open access: yesInternational Journal of Electrochemical Science, 2011
The inhibitory and adsorption potentials of 2-(4-methoxybenzylideneamino) acetic acid (MBDAC), 2-hydroxy-3-methoxybenzaldehyde (HMBA) and 4-methoxybenzaldehyde (MBA) were studied using experimental (gravimetric and gasometric) and computational chemistry

Synthesis and reactivity of aliphatic sulfur pentafluorides from substituted (pentafluorosulfanyl)benzenes

open access: yesBeilstein Journal of Organic Chemistry, 2016
Oxidation of 3- and 4-pentafluorosulfanyl-substituted anisoles and phenols with hydrogen peroxide and sulfuric acid provided a mixture of SF5-substituted muconolactone, maleic, and succinic acids.

Conversion of Alcohols into Amides Using Alumina-Methanesulfonic Acid (AMA) in Nitrile Solvents [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1999
The reaction of tertiary, secondary and benzylic alcohols with different nitriles in the presence of alumina-methanesulfonic acid (AMA) as a new reagent affords the corresponding amides in good yields (Table 1, 2).

Comparative Study of Anisole and 4-Vinylanisole Pyrolysis: Insight into Char, Tar, and Particle Formation During Lignin Pyrolysis

open access: yesPRX Energy
Lignin pyrolysis generates oxygenated aromatics that can serve as renewable biofuel precursors. Anisole and substituted anisoles are widely used as model compounds to probe processes related to their production and use.
