The intra- and intermolecular synthesis of selenium-substituted acyclic and heterocyclic acrylonitrile derivatives is presented. The 1,2-difunctionalization of several internal alkynes substituted not only by aliphatic and aromatic residues but also by heteroelements is realized by the Pd-catalyzed activation of aromatic and aliphatic selenocyanates. A high functional group tolerance allows straightforward

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
