Abstract
The present study describes the cationic oxo-thiolation of polymerizable alkenes by using highly reactive cationic species generated by anodic oxidation. These highly reactive cations were able to activate alkenes before their polymerization. Fast mixing in flow microreactors effectively controlled chemoselectivity, enabling higher reaction temperatures.

Abstract
Difunctionalization of alkenes is a valuable and versatile chemical transformation that could quickly build complex molecules. Extensive efforts have been made, and great achievement, such as Sharpless aminohydroxylation and dihydroxylation, has been reached. However, in marked contrast to the extensive research of aminohydroxylation and dihydroxylation, directly using thiophenols/thiols and O/N-nucleophiles to perform the difunctionalization of alkenes that form the C-S and C-O/N bonds together is still underexplored. The main issue is that thiophenols/thiols are often easily overoxidized to sulfoxides or sulphones under such essential oxidation conditions. We demonstrate an electrochemical oxidative oxysulfenylation and aminosulfenylation of alkenes. A critical feature of this transformation is that neither external chemical oxidants nor metal catalysts are required. This electrochemical oxidative synthetic strategy could also be applied for the hydroxysulfenylation and acyloxysulfenylation of alkenes.

Abstract
Electrochemistry serves as a powerful method for generating reactive intermediates, such as organic cations. In general, there are two ways to use reactive intermediates for chemical reactions: (1) generation in the presence of a reaction partner and (2) generation in the absence of a reaction partner with accumulation in solution as a "pool" followed by reaction with a subsequently added reaction partner. The former approach is more popular because reactive intermediates are usually short-lived transient species, but the latter method is more flexible and versatile. This review focuses on the latter approach and provides a concise overview of the current methods for the generation and accumulation of cationic reactive intermediates as a pool using modern techniques of electrochemistry and their reactions with subsequently added nucleophilic reaction partners.

Abstract
Halogen and chalcogen cations (X(+) = Br(+), I(+), ArS(+), and ArSe(+)) were generated by low-temperature electrochemical oxidation in the presence of dimethyl sulfoxide (DMSO) and were accumulated in the solution. DFT calculations indicated that DMSO stabilizes these cations by coordination. The complexes of I(+) with one and two DMSO molecules were observed by cold-spray-ionization MS analyses. The stability of the resulting cation pools of X(+) increased in the order of Br(+) < I(+) < ArS(+) < ArSe(+), which could be explained in terms of the electronegativity of X. The cation pools served as versatile reagents for organic synthesis; the reactions with alkenes gave β-X-substituted alkoxysulfonium ions, which were converted to the corresponding carbonyl compounds by the treatment with triethylamine, whereas the treatment with methanol gave the corresponding alcohols. The reactions with aminoalkenes and 1,6-dienes gave the cyclized products.
