Abstract

Abstract New phosphorus containing oligomeric compounds of general formula (NR 1CH 2CHR 2OP(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.
