Thus the reaction largely depends upon the stability of the
radical ion formed during the reaction.
Radical and
radical ion reactivity in nucleic acid chemistry.
At almost the same time, the ionized molecule dissociates into a free radical and a
radical ion:
The rate of reaction of superoxide
radical ion with oxyhemoglobin and methemoglobin.
With the exception of the recent and exciting discovery of the conducting and super-conducting properties of alkali metal-doped |C.sub.60~ |1~, most synthetic molecular conductors are based on the use of charged |pi~-radicals, either in the form of charge transfer salts such as TTF TCNQ or
radical ion salts such as those based on the TMTSF and BEDT-TTF donors |2~.
First the polar solvent properties of water tend to promote transient
radical ion formation via ionization or net electron transfers involving the oxidation or reduction of organic species and metal ions.
DW Liquid ROS generates a high concentration of hydroxyl
radical ions that react to form mineral oxides that are inert.
Other topics are molecular structure and reactivity, general principles for writing reaction mechanisms, reactions of nucleophiles and bases, reactions involving acids and other electrophiles, radicals and
radical ions, and pericyclic reactions.
After setting out principles and practice, they cover the photogeneration of carbon-centered radicals, heteroatom-centered radicals, biradicals and radical pairs,
radical ions, carbocations and carbanions, and cargenes and nitrenes.
