ring. To test the assumption if aromatic selenides having Se···X nonbonding interactions can show different types of radical cations, we have performed pulseradiolysisstudies of three structurally related aromatic selenium compounds and the results have been substantiated with cyclic voltammetry and quantum chemical calculations. The three aromatic selenium compounds have functional groups like −CH2N(CH3)2

oxidation of alkyl aryl selenides was studied by means of laser flash photolysis (355 nm). Quenching of the sensitizers in their excited state leads to selenide radical cation in the presence of selenium derivatives. The π-type dimer of methyl phenyl selenide radical cation was detected at 630 nm at expenses of the monomeric radical cation (530 nm). The effect of modification of the aryl and alkyl substituents

A powerful and environmentally friendly electrochemical manganese-promoted free radical selenylation reactionbetween boronic acids and diselenide reagents was established. This electrochemical protocol provides a practically applicable way to a series of valuable organoseleniumcompounds with the use of easy available materials. Mechanistic experiments implied that the seleno-radical formed via direct
