Nucleophilic aromatic substitutions of unactivated aryl halides by methyl selenide anions. Synthesis and selective dealkylations of aryl alkyl selenides
An atom-economical synthesis of unsymmetrical diaryl selenides from arylhydrazines and a stoichiometric amount of diselenides was developed under mild conditions. The new and facile selenide synthesis involved the use of an inexpensive base in air to form unsymmetrical diaryl selenides in good yields. This C-Se radical arylation of diaryl diselenides was performed by forming aryl radicals from arylhydrazines

An efficient protocol to synthesize aryl selenoethers through deborylative selenylation of widely available arylboronicacids has been established underelectrochemicalconditions in the absence of metal catalyst and external oxidant. The synthesis of bioactive molecules and gram-scale transformation have been performed to highlight the synthetic utility of the protocol. CV (cyclic voltammetry) experiment

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
