Electrophilic cyclizations are one of the major strategies for cyclofunctionalizations of alkenes. Selective selenocyclizations can be performed by adjusting various factors in such reactions. The nature of the electrophile, the counterion, solvents, and
Selenocyclizations: Control by Coordination and by the Counterion

Selective cyclizations of selenium electrophiles lead to either tetrahydrofurans or lactones (see scheme), depending on the counterions and additives. Modification of the selenium electrophiles allow selective cyclizations, irrespective of the reaction conditions applied.
