dcterms:description
Treatment of 9- or 7-substituted 6-, 2- or 8-iodopurine derivatives with copper(I) thiophene-2-carboxylate or copper(I) 3-methylsalicylate in N,N-dimethylformamide affords the corresponding 6,6´-, 2,2´- and 8,8´-purine dimers in high yield. Attempts at cross-dimerization of different iodo derivatives lead only to mixtures containing the cross-coupled products, homodimers or dehalogenation products. The crystal structures of 9,9'-dibenzyl- (1a) and 9,9'-bis(1-methylethyl)-9H,9'H-[6,6']bipurinyl (1c), and the salt [1aH2]Br2 have been determined by single-crystal X-ray diffraction analysis, revealing extensive hydrogen bonding and pxxxp stacking interactions.
