An Interrupted Vinylogous Iso-Nazarov Reaction: Cycloisomerization of Conjugated Trienones to Cyclopenta[b]furan Derivatives
(American Chemical Society, 2014-05)
Iron(III) chloride-catalyzed cyclopentannulation of π-conjugated 1,3-dicarbonyl compounds is described. An interrupted vinylogous iso-Nazarov reaction of trienones was established in which cyclopenta[b]furan derivatives ...
Furan resins as replacement of phenolic protective coatings: Structural, mechanical and functional characterization
(Elsevier, 2013-10-27)
Phenolic coatings are usually a convenient and economical way to protect metallic materials against wear and corrosion. Furan resins are analogous to phenolics, as they are obtained by replacing formaldehyde by furfural ...
Cycloisomerization of Conjugated Trienones and Isomeric 2 H -Pyrans: Unified Strategy toward Cyclopenta[ b ]furans
(American Chemical Society, 2015-06)
Conjugated trienones and isomeric 2H-pyrans were found to engage in a novel cycloisomerization cascade toward cyclopenta[b]furan derivatives. Knoevenagel chemistry and pericyclic reactions meet again to expand the ...
Alkyl carbonate derivatives of furanics: A family of bio-based stable compounds
(Elsevier Science, 2021-04)
Several alkyl carbonate derivatives of 5-hydroxymethylfurfural (HMF) and 2,5-bis(hydroxymethyl)furan (BHMF) have been synthesized for the first time. In most cases high yields were achieved using mild reaction conditions ...
Predicting furan content in a fried dough system using image analysis
(2019)
The aim of this paper is to test different models for predicting furan content in a dough system, based
22 on partial least squares regression using colour images. Starch dough systems were fried at five
23 temperatures ...
Novel Thiosemicarbazone Derivatives from Furan-2-Carbaldehyde: Synthesis, Characterization, Crystal Structures, and Antibacterial, Antifungal, Antioxidant, and Antitumor Activities
(Hindawi, 2023)
Ten new thiosemicarbazone derivatives, furan-2-carbaldehyde thiosemicarbazone (1), 3-methyl-furan-2-carbaldehyde thiosemicarbazone (2), 5-hydroxymethyl-furan-2-carbaldehyde thiosemicarbazone (3), 5-trifluoromethyl-furan- ...
Molecular vibrational constants and chemical bonding in five-membered heteratomic compounds
(1985)
By means of the force field and mean amplitudes of vibration of furan, thiophene, selenophene and tellurophene molecules, we have concluded that the ground-state aromaticity order in the series is thiophene > tellurophene ...
Furan as Impurity in Green Ethylene and Its Effects on the Productivity of Random Ethylene–Propylene Copolymer Synthesis and Its Thermal and Mechanical Properties
(Cartagena de Indias, 2023)
The presence of impurities such as H2S, thiols, ketones, and permanent gases in propylene of fossil origin and their use in the polypropylene production process affect the efficiency of the synthesis and the mechanical ...
