Abstract
Different approaches to the synthesis of ω-(organylchalcogeno)alkyl phosphonates were examined. It is established that diethyl 2-(organylseleno (telluro))ethyl- and 4-(organyl-thio(seleno, telluro))butyl phosphonates are formed by nucleophilic substitution of bromine in diethyl 2-bromoethyl- and 4-bromobutyl phosphonates with chalcogenolate anions generated from the corresponding diorganyl dichalcogenides. The 1H and 31P NMR spectra of these phosphonates are discussed.
