Abstract

Bis[(dimethoxyphosphoryl)methyl)]amino- and bis(phosphonomethyl)amino-terminated samples of poly(ethylene glycol) (PEG) were prepared from commercially available PEG in fair-to-good yields by means of adaptations of the Moedritzer–Irani and Kabachnik–Fields procedures, respectively. An alternative route involving silylation of phosphonates and subsequent meth­anolysis to afford phosphonic acid groups was also examined.
