The electron affinity trends observed for the title compounds indicate that in 1.4-cyclohexadiene the A, anion state, arismg from electron capture into the out-of-phase combination of the empty ethenic v\* MOs, lies at lower energy than the B,, anion state, correlated with the in-phase combination.
## Abstract Radical anions of alkyl α‐oxocarbothioates and α‐oxocarbodithioates are generated by __in situ__ electroreduction. Their spin density distribution and configuration are discussed in terms of the ESR spectra and semi‐empirical (McLachlan‐type and AM1) MO calculations.
