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.

Hydrophobically modified polyelectrolytes as potential drugs reservoirs of n-alkyl-nitroimidazoles [PDF]

open access: yes, 2007
Indexación: ScieloThe solubilization of three commercial drugs (ornindazole, metronidazole and tinidazole) and model compounds (N-alkyl-2-methyl-4-nitroimidazoles) on aggregates formed by anionic polyelectrolytes, carrying alkyl side chains of different ...

Influence of diluent alkyl substitution on the extraction of Am(III) and Eu(III) by a 6,6’-bis(1,2,4-triazin-3-yl)-2,2’-bipyridine ligand dissolved in alkylated cyclohexanone Diluents [PDF]

open access: yes, 2012
Several alkylated cyclohexanones were investigated as potential diluents for the selective extraction of Am(III) from Eu(III) from nitric acid solutions by the CyMe4-BTBP ligand.

[Bis(Trimethylsilyl)Methyl]Lithium and -Sodium: Solubility in Alkanes and Complexes with O- and N- Donor Ligands

open access: yesInorganics, 2017
In contrast to alkyl compounds of lithium, which play an important role in organometallic chemistry, the corresponding heavier alkali metal compounds are less investigated.

Synthesis of long-chain alkyl and alkenyl bromides

open access: yesJournal of Lipid Research, 1966
Long-chain alkyl and alkenyl bromides are obtained in quantitative yields by the reaction of methanesulfonates with anhydrous magnesium bromide in absolute ether; cis-trans isomerization of double bonds does not occur.

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

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.

Copper(0)-mediated radical polymerisation in a self-generating biphasic system [PDF]

open access: yes, 2013
Herein, we demonstrate the synthesis of well-defined poly(n-alkyl acrylate)s via copper(0)-mediated radical polymerisation in a self-generating biphasic system. During the polymerisation of n-butyl acrylate in DMSO, the polymer phase separates to yield a

The alkyl moieties in wax esters and alkyl diacyl glycerols af sharks

open access: yesJournal of Lipid Research, 1971
The alkyl moieties in wax esters and alkyl diacyl glycerols from the liver of the dogfish, soupfin shark, and silky shark are almost exclusively saturated and monounsaturated, the main alkyl moieties being the C16 and C18 chains in both lipid classes ...

Room-Temperature Alternative to the Arbuzov Reaction: The Reductive Deoxygenation of Acyl Phosphonates [PDF]

open access: yes, 2010
The reductive deoxygenation of acyl phosphonates using a Wolff−Kishner-like sequence is described. This transformation allows direct access to alkyl phosphonates from acyl phosphonates at room temperature. The method can be combined with acyl phosphonate
