Zs. Cheruvallath et al., Use of phenylacetyl disulfide (PADS) in the synthesis of oligodeoxyribonucleotide phosphorothioates, NUCLEOS NUC, 18(3), 1999, pp. 485-492
Investigations into the use of phenylacetyl disulfide (PADS) as an efficien
t sulfur transfer agent in the solid phase synthesis of oligodeoxyribonucle
otide phosphorothioates showed that under suitable solvent conditions, this
relatively inexpensive reagent rapidly and efficiently sulfurizes internuc
leotide phosphite linkages.
