Variously substituted S-glycosides react in acetonitrile with the primary or secondary hydroxy group of O-glycosides in the presence of tris (4-bromophenyl)ammoniumyl hexachloroantimonate, a stable and commerically available radical cation, to give the corresponding β-O-linked disaccharides in high yield.

Abstract
Variously substituted S-glycosides react in acetonitrile with the primary or secondary hydroxy group of O-glycosides in the presence of tris (4-bromophenyl)ammoniumyl hexachloroantimonate, a stable and commerically available radical cation, to give the corresponding β-O-linked disaccharides in high yield.File in questo prodotto:
