Abstract
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.
