    摘要: A method and compositions for sulfurizing at least one phosphite or thiophosphite linkage in an oligonucleotide. The methods employ a phenylacetyl disulfide reagent (known as PADS), phenylthioacetic acid (PTAA) in the presence or absence or N-alkyl imidazole in industrially preferred solvents or solvents that are derived from renewable resources. The use of PTAA eliminates the need to “age” the PADS solution prior to its use in sulfurization reactions.
