✦ Synopsis

New phosphorus containing oligomeric compounds of general formula (NR*CH2CHR2OP(O)R)., analogous to polypeptides, were isolated and characterised. These are stable intermediaries in the acid catalysed imide-amide ttma'angement of cyclic phosphorimidates through a ring-opening polymerisation, revealing an intermolecular two step mechanism for this rearrangement.
