Abstract
The action of LiEt 3 BH or DIBAL-H on various functionalized selenocyanates was proven to be an efficient means to establish chemoselectively the diselenide bond, under very mild conditions. The mechanism was shown to involve a selenophilic hydride attack rather than a carbophilic one, supporting a selenol as the intermediate to the diselenide. The action of LiEt 3 BH or DIBAL-H on various functionalized selenocyanates is proven to be an efficient means to establish chemoselectively the diselenide bond, under very mild conditions.
