Kinetics and mechanisms of the reactions of organic cation radicals and dications. IV. First- and second-order reactions of thianthrene cation radical with phenol

Cationic Polymerization Induced by Tris-(p-bromophenyl) Amine Cation-Radical Salts

“…For cyclohexene oxide polymerization, the chain transfer process could be represented as in Scheme 2 [16,17]. The mechanism for initiation of the polymerization of cyclohexene oxide by ammoniuymyl salt (3), and consistent with the reports on the reactions of cation radicals with weak nucleophiles [18], is shown in Scheme 4 below. Polymer chains would grow (and undergo transfer to monomer) as indicated, following thermal initiation by both the protonic acid produced and the amine ended cyclic oxonium ion.…”

Voltammetry: doing chemistry with electrodes

“…This technique has been applied to other anodic reactions in which even more complex rate laws have been found. [44][45][46] Similar ECE schemes are operative in the reduction of quiñones in the presence of proton donors. 47 The foregoing journey through recent work in electrochemistry shows that many electrode reactions fall in the class of weakly interacting systems in which the electrochemically generated intermediates diffuse into solution where they display their inherent chemical properties.…”

Spectrophotometric Kinetic and Mechanistic Investigation of Chlorpromazine Radical Cation with Hexachloroiridate (IV) in Catalyzed Aqueous Acid Medium

“…In late years, there has been significant interest in these drugs due to the reactivity of phenothiazine as neutral as well as radical cationic [4][5][6] form, and some interesting mechanistic approaches of these radical with nucleophiles have been investigated. [7][8][9][10][11][12] The mainly used Phenothiazine based drugs are substituted at the position 2 and 10, [13] and the types of substituent have chemical and reactivity properties of these compounds governing their uses.…”
