Synthetic strategies of gold(I)-selenolates from ortho-substituted diaryl diselenides via selenol and selenenyl sulfide intermediates

In the present study we describe the synthetic strategies to gold(I)-selenolate complexes by the reaction of ortho-substituted diaryl diselenides and electrophilic anti-arthritic gold(I)-compounds in the presence of thiol such as PhSH. Diselenides react with thiol to generate a mixture of selenol and selenenyl sulfide. While selenols react with electrophilic Au(I) compounds to form gold(I)-selenolate complexes, the selenenyl sulfides do not...
