Abstract
A straightforward and efficient electrochemical method for the anodic oxidative selenenylation of 2-(2-arylallyl)phenols and a 2-(3-arylbut-3-en-1-yl)phenol with diselenides under ambient air conditions has been outlined. This method allows for the synthesis of selenyl-dihydrobenzofurans and a chromane featuring a sterically hindered tetrasubstituted carbon center, demonstrated through 25 examples with yields reaching up to 98%. Initial mechanistic investigations suggest the likely participation of pivotal seleniranium cation species in regulating the reactivity.
