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.
分离并表征了新的类似于多肽的通式(NR 1 CH 2 CHR 2 OP(O)R)n的含磷低聚物。这些是通过开环聚合反应在环状磷酸亚胺的酸催化的酰亚胺-酰胺重排中的稳定中间体,揭示了这种重排的分子间两步机理。
