Oxidative addition reactions and hydrogen abstraction from the coordinated ligand Reactions with CO, PF3, NO, and HCl are described. Reaction of IrCl(Ph3P)3 with chlorine gives initially an iridium(III) complex IrCl3(Ph3P)2, which appears to be five-coordinate in solution, and with excess ...
In recent years, the electrochemistry-induced reactions have drawn much attention due to the high reaction efficiency, innate scalability and sustainability of the electrolytic process41,42,43,44,45,46,47. The past decade has witnessed the rapid development of difunctionalization of unsaturated bonds i...
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

Introduction Bacterial biofilms are becoming a prevailing area of microbial research as their ubiquitous presence and influence across artificial and natural environment...
The replacement of hydrogen by a halide in the aromatic ring proceeds predominantly in the para position and is inhibited by nitrobenzene. 3. Reaction schemes were proposed entailing the formation of the benzyl radical and σ -complexes of toluene with a chlorine atom which are converted ...

Neutrophils and other phagocytes manufacture O 2 − (superoxide) by the one-electron reduction of oxygen at the expense of NADPH. Most of the O 2 − reacts with itself to form H 2O 2 (hydrogen peroxide). From these agents a large number of highly reactive microbicidal oxidants are fo...
Cyanide is itself a very toxic and reactive species that under certain conditions (e.g., low pH) can produce equally toxic hydrogen cyanide gas. It is necessary, therefore, to destroy the cyanide before disposal of the waste. Cyanide is generally destroyed by its oxidation with chlorine under...
In Eqn (22.4), chlorine is oxidized from +1 to +3 because the +2 oxidation state is not normally accessible for that atom. Note that in each of these reactions, the number of bonds to the central atom is increased by two. In the reaction shown in Eqn (22.3), sulfur increases in ...
Compositions prepared from (I) an iron group-containing component, such as nickel oxide, (II) a Group VIB-containing component, such as of molybdenum, and (III) a Group VA-containing component, such as a phosphorus, arsenic, or antimony, are effective in a process to convert paraffins or ...
