Synthesis of long-chain alkyl and alkenyl bromides

Journal 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.

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

Journal 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 ...

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

, 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

Enantioselective C(sp3)–C(sp3) cross-coupling of non-activated alkyl electrophiles via nickel hydride catalysis

Nature Chemistry, 2020
Cross-coupling of two alkyl fragments is an efficient method to produce organic molecules rich in sp3-hybridized carbon centres, which are attractive candidate compounds in drug discovery.

Inhibitory Activities of Alkyl Syringates and Related Compounds on Aflatoxin Production

Toxins, 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

Ceramics, 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]

, 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

Journal 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 ...

Antibacterial activity of alkyl gallates is a combination of direct targeting of FtsZ and permeabilization of bacterial membranes

Frontiers in Microbiology, 2015
Alkyl gallates are compounds with reported antibacterial activity. One of the modes of action is binding of the alkyl gallates to the bacterial membrane and interference with membrane integrity.

Fragment Coupling and the Construction of Quaternary Carbons Using Tertiary Radicals Generated From tert-Alkyl N-Phthalimidoyl Oxalates By Visible-Light Photocatalysis. [PDF]

, 2015
The coupling of tertiary carbon radicals with alkene acceptors is an underdeveloped strategy for uniting complex carbon fragments and forming new quaternary carbons.
