Tlw mechaflism of iodination of C2- and C3-atoms of ribofuranose In pyrimidine nudeosides in conditions of Arbuzov reaction have been studied. Intermediate 2'- and 3''-quaziphosphonium salts where, shown, to be involved in further intramolecular nudeophilic reactions, the resulting 2',3'-diiododerivative being deiodinated and transformed into correspondent 2',3'-didehydro-2'-3'-dideoxynuc-leosides.
