agent, bis-(p-nitrophenylethyl)phoshoromonochloridate, has been prepared and is used for 3′- and/or 5′-phosphorylations of nucleosides. The resulting bis-(p-nitrophenylethyl)phosphotriesters are versatile synthons in oligonucleotide syntheses leading finally to 3′- and/or 5′-terminated oligonucleotides in excellent yields.
