New phosphorus containing oligomeric compounds of general formula (NR1CH2CHR2OP(O)R)n, analogous to polypeptides, were isolated and characterised. These are stable intermediaries in the acid catalysed imide-amide rearrangement of cyclic phosphorimidates through a ring-opening polymerisation, revealing an intermolecular two step mechanism for this rearrangement.
