Efficient phenylsulfenylation and phenylselenenylation at the 5-position of uracil nucleosides with disulfide and diselenide mediated by [bis(trifluoroacetoxy)iodo] benzene
A series of uracil nucleosides reacted with diphenyl disulfide or diphenyl diselenide in the presence of hypervalent iodine reagent, [bis(trifluoroacetoxy)iodo]benzene, in acetonitrile to give the corresponding C-5 phenylsulfenylated or phenylselenenylate
