nucleotides (pN) with activated monomers (ImpN), the sequence- and regioselectivity was Pu(3')Py > Pu(3')Pu = Pu(2')Py > Pu(2')Pu. The 5'-pyrimidine initiated dimers formed less efficiently than the 5'-purine initiated dimers. Trimer formation was investigated by the synthesis of 8 dimers (pNpN) and measuring the yields of trimers formed in the reaction of each dimer with a mixture of equal molar amounts

polymerization of cytidine 5′-phosphorimidazolide in aqueous solution. 2′–5′ internucleotidelinkage was preferentially formed. The yields of the 2′–5′ linked dimer, trimer, tetramer and pentamer were 17.0, 5.5, 1.9, and 0.7%, respectively. Some of their properties were studied by NMR, CD, UV, and chromatography and compared with the corresponding 3′–5′ linked oligomers which were prepared enzymatically.
