In some embodiments, provided methods comprise reacting an H-phosphonate of structure Ia or Ib with a silylating reagent to provide a silyloxyphosphonate, and reacting the silyloxyphosphonate with a thiosulfonate reagent of structure IIa or IIb to provide an oligonucleotide of structure IIIa or IIIb. In some embodiments, provided methods comprise reacting an H-phosphonate of structure Ic with a silylating reagent to provide a silyloxyphosphonate, reacting the silyloxyphosphonate with a bis(thiosulfonate) reagent of structure IVc to provide a phosphorothiotriester comprising a thiosulfonate group of structure Vc, and then reacting the phosphorothiotriester comprising a thiosulfonate group of structure Vc with a nucleophile of structure VIc to provide an oligonucleotide of structure IIIc.
