Establishment of salicylic acid derived silylation reagents for protection of alcohols

open access: yesResults in Chemistry, 2021
In this work, we describe salicylic acid derived 2-[(trimethylsilyl)oxy]-benzoic acid methyl ester (TMSSME) and its TBDMS- (TBDMSSME) and TIPS-analogous (TIPSSME) as novel silylation reagents to furnish silyl ethers from alcohols.

Microcellular Poly (Ethylene‐Co‐Vinyl Acetate)/Lignin Nanocomposites for Soft Ferroelectrets

open access: yesAdvanced Engineering Materials, EarlyView.
Lignin valorization for advanced porous polymer nanocomposites development and an upscaling route for continuous manufacturing of soft ferroelectrets for energy harvesting are studied. This work examines the role of lignin and carbon nanotubes (CNT) in modifying the mechanical, dielectric, and ferroelectret properties of poly (ethylene‐co‐vinyl acetate)

Synthesis of novel 2-methyl-3-triazolyl chromanone oxime etherderivatives as potential antifungal agents [PDF]

open access: yesJournal of Mazandaran University of Medical Sciences, 2006
Background and purpose: Despite growing list of antifungal agents, their clinical value has been limited by their relatively high risk of toxicity, the emergence of drug resistance, and insufficiencies in their antifungal activity. This situation has led

Composition of the diacyl glyceryl ethers and triglycerides of the flesh and liver of the dogfish (Squalus acanthias)

open access: yesJournal of Lipid Research, 1965
The major lipids of the dogfish (Squalusacanthias) are the diacyl glyceryl ethers and triglycerides. These classes of compounds in the flesh (dorsal section) and liver were separated by thin-layer chromatography.

Methyl and Ethyl Ethers of Glycerol as Potential Green Low-Melting Technical Fluids

open access: yesMolecules, 2023
The study is dedicated to the consideration of lower alkyl ethers of glycerol as potential components of low-melting technical fluids (e.g., heat transfer fluids, hydraulic fluids, aircraft de-icing fluids, etc.).

The co-pyrolysis of flame retarded high impact polystyrene and polyolefins [PDF]

open access: yes, 2007
The co-pyrolysis of brominated high impact polystyrene (Br-HIPS) with polyolefins using a fixed bed reactor has been investigated, in particular, the effect that different types brominated aryl compounds and antimony trioxide have on the pyrolysis ...

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Stereodivergent approach in the protected glycal synthesis of L-vancosamine, L-saccharosamine, L-daunosamine and L-ristosamine involving a ring-closing metathesis step

open access: yesBeilstein Journal of Organic Chemistry, 2018
In this paper, a new access to several chiral 3-aminoglycals as potential precursors for glycosylated natural products is reported from a common starting material, (−)-methyl-L-lactate.

Dehydration of n-propanol and methanol to produce etherified fuel additives

open access: yesAIMS Energy, 2017
An ether is an organic compound that consists of an oxygen atom bonded to two alkyl or aryl groups. In this work, we investigate the bimolecular dehydration of two alcohols, n-propanol and methanol with catalysts that are used in transesterification ...

Photochemistry of N-(selenoalkyl)-phthalimides. Formation of N, Se-heterocyclic systems [PDF]

open access: yes, 2015
A variety of N-(selenomethyl)alkyl-phthalimides (alkyl = -(CH2)n-; n = 2-5, 1a, b, d, e) and N-(selenobenzyl)propyl phthalimide (1c) were synthesized and their photochemistry was studied at λ = 300 nm.
