1
The Porphyrin Handbook: Biochemistry and binding: activation ...
Upon the change of the solvent to benzene or toluene, a remarkable mechanistic
change was observed.4211-44 In these solvents, the O-O bond cleavage
changed to favor homolysis. Thus, the push-pull effect on the homolysis was also
...
Karl M. Kadish, Kevin M. Smith, Roger Guilard, 2000

Free Radicals and Oxidation Phenomena in Biological Systems
A.a. Bond Homolysis Any organic molecule which possesses an even number of
valence electrons can theoretically split to produce two radicals if a covalent
bond in the molecule can be broken so as to provide each part of the molecule
one ...

Cholesterol Autoxidation
Peroxide bond homolysis may occur via several means, through natural
instability, thermal sensitivity, transition metal ion catalysis, etc. Uncatalyzed
peroxide bond homolysis yielding alkoxyl and hydroxyl radicals, as represented
in m.

Enzyme-Catalyzed Electron and Radical Transfer
Stopped Flow Studies of Adenosylcobalamin Homolysis The u.v.-visible
spectrum of the coenzyme changes significantly upon homolysis of the CoóC
bond: AdoCbl is pink, a characteristic of the 6coordinate Co(III) atom, whereas
Cbl(II) is ...
Andreas Holzenburg, Nigel S. Scrutton, 2000

Vitamin B 12 and B 12-Proteins
Despite this fact, when we began these studies, neither the thennaf homolysis
products, nor the desired kinetic and bond dissociation energy (BDE) studies,
had been reported for any of the following important alkyl-B12 complexes,
studies ...
Bernhard Kräutler, Bernard T. Golding, Duilio Arigoni, 2008

Tetrapyrroles: Birth, Life and Death
In the "DMB-on" subclass of isomerases, the solution conformation of the cofactor
is maintained (B). enthalpy is 31.4 ±1.5 kcal mol"1 for AdoCbl and the thermal
homolysis rate at 25°C is only 1 0"9 * ' s" , representing a half-life of one year at ...
Martin Warren, Alison Smith, 2009

Nitric Oxide: Biology and Pathobiology
Peroxynitrite can undergo proton-catalyzed homolysis (Beckman et al., 1990;
Radi et al., 1991b) to •NO 2 and •OH in 30% yields, with an observed first-order
rate constant of 1 s–1 at pH 7.4 and 37°C and a pH-independent rate constant of
...
Peroxides undergo homolysis of the weak O—O bond extremely easily to form
two radicals. We said that HCl in the gas phase undergoes homolysis in
preference to heterolysis: other types of bond are even more susceptible to
homolysis.
Jonathan Clayden, Nick Greeves, Stuart Warren, 2012

Organic Chemistry: A Mechanistic Approach
20.1 Homolysis There are two types ofbond cleavage, homolysis and heterolysis,
as discussed in Section 7.2. In homolysis, the electrons of a σ bond between two
atoms become unpaired to give two radicals, each with an unpaired electron.
Tadashi Okuyama, Howard Maskill, 2013

Advances in Gas Phase Ion Chemistry
With regard to single bond cleavages, the terms homolysis and heterolysis are
well understood. When the electron pair in a covalent bond splits between two
fragments, the cleavage is a homolysis. When one fragment retains both
electrons, ...
