Deprotection of sulfonimidamides with formic acid in a long period of reaction time (hours to days) leads to the formation of the unexpected oligomeric sulfonimidamides. This work demonstrates that an unprotected sulfonimidamide can also undergo a similar oligomerization in a neutral solvent. The results show that oligomerization is an inherent property of sulfonimidamides.

齐聚：磺酰胺的固有性质？

在长时间的反应时间（数小时至数天）中，用磺酸对亚磺酰胺酰胺进行脱保护，导致形成意想不到的低聚亚磺酰胺。这项工作表明，未保护的磺酰亚胺酰胺也可以在中性溶剂中进行类似的低聚反应。结果表明，低聚是磺酰亚胺酰胺的固有性质。
