The water absorption of papers which are free of aluminum sulfate can also be reduced.

Hydrogen atom transfer oxidation of primary and secondary alcoholates into aldehydes and ketones by aromatic halides in liquid ammonia. A new electrochemically induceable reaction

Abstract: It is possible to induce the oxidation of alcoholates into the corresponding carbonyl compounds by electrochemical reduction of aromatic halides in liquid ammonia, Le., to electrochemically trigger the reaction ArX + >CH-OArH + >C=O + X-. H-Atom transfer from the alcoholate to the aryl radical formed upon reduction of the aryl halide appears as the key step of the oxidation process. The ketyl anion radical thus formed can be oxidized into the parent carbonyl compound, remain electrochemically stable, or be reduced into the dianion depending upon the location of the two corresponding standard potentials toward the reduction potential of the aryl halide. Electricity consumption thus tends toward 0, 1, and 2 F/mol for the three cases, respectively. The reactions competing with H-atom transfer, thus lowering the efficiency of the electrochemical inducement of the oxidation process, are electron transfers to the aryl radical which occur at the electrode surface and/or in the solution. These will play the role of termination steps for the corresponding chain systems involving homogeneous initiation of the reaction. The kinetic analysis of the competition between H-atom transfer and homogeneous or heterogeneous electron transfer allows a detailed investigation of the reaction mechanism by electrochemical techniques such as cyclic voltammetry. This also leads to the determination of the rate constant of H-atom transfer of the alcoholate-aryl radical couple. Electrochemical inducement of a chemical reactionza is based upon the reactivity of the system being larger at a higher or a lower oxidation level than at the original one. A few examples of such processes have been described in organic or coordination chemistry? This reaction that has been the most extensively studied in this respect is SRNl aromatic nucleophilic s~bs t i t u t ion ,~ the electrochemical inducement”Sk of which is based on the following reaction sequence: ArX + l e 9 ArX-. ArX-. Ar. + XAr. + NuArNu-.

Evidence for the intermediacy of the aryl radical in the Sandmeyer reaction

Abstract: The competition between bromodediazoniation and chiorodediazoniation is exploited as a test of the occurrence of an aryl radical in the Sandmeyer reaction pathway. The use of five reducing agents, covering a wide range of redox ability, is shown not to influence the experimental kBr/kCl values. The intermediacy of a common species is consequently inferred and supported by independent generation of the phenyl radical by decomposition of benzoyl peroxide. Considerations on the rates of the ligand transfer processes are put forward.

Triplet state electron spin resonance studies of aryl cations. Part 5.—The aryl cation/aryl radical product ratio in photolysis of arenediazonium salts at 77 K1

Abstract: An e.s.r. study has been made of the factors (solute concentration, matrix, irradiation wavelength and time, post-photolysis storage) affecting the relative yields of 3Ar+ and Ar˙ in the photolysis of an arenediazonium salt at 77 K. The principal findings are: (i)(in contrast with the situation prevailing in solution) photoheterolysis is the sole primary process; (ii) production of Ar˙ during irradiation comes from photoreduction of 3Ar+; (iii) there is a very powerful solute-concentration dependence of the photo-conversion of 3Ar+ into Ar˙(which does not proceed at very low solute concentrations); (iv) conversion of 3Ar+ into Ar˙ proceeds slowly in the dark. Mechanistic aspects of these observations are discussed.
