Tricyclohexylsilaneselenol (168) can be coupled with aryl halides in the presence of a catalyst formed from palladium(II) acetate and 2-(dicyclohexylphosphino)-2,6-diisopropoxybiphenyl (RuPhos; Scheme 63). Aryl chlorides are incompatible with this procedure, but aryl bromides and iodides are efficiently converted into selenoacetates 169 at room temperature by treatment of the tricyclohexyl-protected areneselenol intermediates with tetrabutylammonium fluoride and acetyl chloride. Exceptions to this general trend are substrates possessing a nitro group or an enolizable carbonyl moiety.[‌277‌]
