A special attention is given to chlorine dioxide interaction with alkyl, aryl, heteroaryl, monoterpenyl thiols, sulfides and disulfides. The data on the oxidation of monoterpene alcohols and phenols are also presented. The directions of reactions depending on the structure of the compounds were ...
Chemical halogenation is an important transformation in organic synthesis. Halogenations involve the use of reactive and toxic halogens (X2) or hydrogen halides (HX). Chemical halogenations are fast and exothermic, but with little regio- or stereoselecti
Chlorine content and position of chlorinated phenols have many significant effects on the reactivity of oxido-reduction. The effects of chlorine content an... ZHANGJin LIGui-bai - 《环境科学学报(英文版)》 被引量: 24发表: 2003年 Structural Effects of Varied Steric Bulk in 2,(4),6-Substituted...
The intracellular production or accumulation of oxidizing agents leads to oxidative stress [22]. The most biologically abundant and clinically relevant reactive molecules include reactive oxygen, chlorine, nitrogen, and sulphur species (ROS, RCS, RNS, and RSS, respectively). While the oxidant effect ...
(19). With respect to nucleophile coupling partner, we selected 4-fluorobenzenethiol1to interrogate the performance of a range of alcohols, azoles and acids under the electrochemical conditions. The catalytic efficiency of the reaction showed little effect on the chain length of primary alcohols (20...

Cleavage ofalkynesinvolves breaking triple bonds, similar to double bonds, using strong oxidizing agents like chromic acid or ozone. Thisreactionresults in carboxylic acids for carbon chains longer than one and carbon dioxide for single carbon chains. For example, atriple bondwith three carbons on ...
Examples of nonionic surfactants include alkoxylated alcohols or ethers, alkoxylated carboxylic acids, sorbitan derivatives, and the like. Alkoxylated alcohols, or ethers, are formed by the reaction of an alcohol with an alkylene oxide, usually ethylene or propylene oxide. Preferably the alcohol is a...
the source of halogen may be used in an amount that is greater or less than the stoichiometric amount, if desired. In one embodiment illustrative of the invention, propane can be oxidatively chlorinated with chlorine to form chloropropane and hydrogen chloride, the stoichiometric reaction of which ...
With the global phase-out of the phosgenation processes, oxidative carbonylation of alcohols to synthesize short-chain dialkyl carbonates (especially DMC, DEC) is considered as a promising route under the guidance of "green chemistry." Despite the good initial performance of chlorine-containing ...
