Triphilic ionic-liquid mixtures: fluorinated and non-fluorinated aprotic ionic-liquid mixtures [PDF]

open access: yes, 2015
We present here the possibility of forming triphilic mixtures from alkyl- and fluoroalkylimidazolium ionic liquids, thus, macroscopically homogeneous mixtures for which instead of the often observed two domainspolar and nonpolarthree stable microphases ...

Nickel-Catalyzed Cross-Electrophile Coupling of Aryl Chlorides with Primary Alkyl Chlorides.

open access: yesJournal of the American Chemical Society, 2020
Alkyl chlorides and aryl chlorides are among the most abundant and stable carbon electrophiles. Although their coupling with carbon nucleophiles is well developed, the cross-electrophile coupling of aryl chlorides with alkyl chlorides has remained a ...

Ring Opening Reactions through C-O Bond Cleavage Uniquely Adding Chemical Functionality to Boron Subphthalocyanine

open access: yesMolecules, 2015
We are reporting the unexpected reaction between bromo-boron subphthalocyanine (Br-BsubPc) and THF, 1,4-dioxane or γ-butyrolactone that results in the ring opening of the solvent and its addition into the BsubPc moiety.

Measurements of PAN, alkyl nitrates, ozone, and hydrocarbons during spring in interior Alaska [PDF]

open access: yes, 1996
Measurements of the atmospheric mixing ratios of ozone, peroxyacetylnitrate (PAN), hydrocarbons, and alkyl nitrates were made in a boreal forest ecosystem in the interior of Alaska from March 15 to May 14, 1993.

Land use affects the soil C sequestration in alpine environment, NE Italy [PDF]

open access: yes, 2017
Soil carbon sequestration is strongly affected by soil properties, climate, and anthropogenic activities. Assessing these drivers is key to understanding the effect of land use on soil organic matter stabilization.

Transition metal–catalyzed alkyl-alkyl bond formation: Another dimension in cross-coupling chemistry

open access: yesScience, 2017
Stitching one alkyl group to another Chemical reactions such as Heck and Suzuki coupling facilitate access to an enormous range of relatively flat molecules. This geometrical constraint is associated with the comparative ease of linking together aryl and

Synthesis and Thermal Behaviour of Calcium Alkyl Phosphates as Bioceramic Precursors

open access: yesCeramics, 2022
Powders of alkyl phosphoric acids and calcium alkyl phosphates with various alkyl chains (butyl, octyl, and dodecyl) have been synthesized. The resulting powders were characterized by X-ray phase analysis, electron microscopy, and thermal analysis.

Few layer 2D pnictogens catalyze the alkylation of soft nucleophiles with esters [PDF]

open access: yesNat. Commun. 2019, 10, 509, 2019
Group 15 elements in zero oxidation state (P, As, Sb and Bi), also called pnictogens, are rarely used in catalysis due to the difficulties associated in preparing well-structured and stable materials. Here, we report on the synthesis of highly exfoliated, few layer 2D phosphorene and antimonene in zero oxidation state, suspended in an ionic liquid ...

Inhibitory Activities of Alkyl Syringates and Related Compounds on Aflatoxin Production

open access: yesToxins, 2016
Inhibitors of aflatoxin production of aflatoxigenic fungi are useful for preventing aflatoxin contamination in crops. As methyl syringate weakly inhibits aflatoxin production, aflatoxin production inhibitory activities of additional alkyl syringates with
