Reactions of a benzylideneaniline radical anion have been studied by spectral and product analyses, in which successive irradiation of uv-light and ionizing radiation at low temperature have been applied to the production of the unstable syn-radical

A one-electron reduction of 1-benzoyl-ω-haloalkane (Cl, Br, I) by solvated electrons and a subsequent intramolecular reaction of the radical anions, thus formed, have been investigated by using a pulse radiolysis technique. The reaction mechanism, e

The cycloreversion of trans,syn- and cis,syn-indene dimers (I and II) occurred upon γ-radiation of n-butyl chloride solutions. The effects of additives and high G values for formation of indene demonstrated that the cycloreversion proceeds by means

γ-Radiolysis of triphenylcyanocyclobutane (1) in benzene forms stilbene, cinnamonitrile and a stereo isomer of 1. The effect of additives and the kinetic treatment show that the cycloreversion of 1 proceeds by benzene triplet sensitization. Spectros

Hydroxylation of 2,4,6-trideuteriotoluene by O(3P) atoms gave mixtures of tri- and di-deuteriocresol in liquid phase and in gas phase. The retention values of deuterium of aromatic ring in cresols produced by the hydroxylation were similar to those r

The structure of the C7H7+ ion formed by γ radiolysis of cycloheptatriene vapor has been investigated by an ion-trapping with toluene-d8 or dimethylamine. The C7H7+ ion was shown to be mainly a rearranged benzyl type while a tropylium ion was also t

In the γ-radiolysis of 1,4-cyclohexadiene vapor at room temperature, the contribution of neutral and ionic intermediates to the main products has been investigated by the application of electric fields and by the addition of nitrous oxide and ammoni

In the gas-phase radiolysis of a CH4(100 mm)–C6H6(5 mm)–C6D6(5 mm) mixture, an H-D exchange was observed in reactant benzene; the G value of the H-D exchanged benzenes was 69. The result has been attributed to the proton exchange reaction of the
