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 external additives coordinating to the electrophilic species are used to control the course of such cyclizations with high degrees of efficiency.
