A ‘Se'lling point: The first thermally induced OAr→SeAr migration reaction is reported, and it can be used to prepare aryl selenols in three steps from the corresponding phenols. O-aryl selenocarbamates rearrange to Se-aryl carbamates via a four-membered transition state (see scheme). The aryl selenols (isolated as the diselenides) can be prepared by hydrolysis of the Se-aryl selenocarbamates.
