Sulfonyl azides are widely documented in chemical literature as effective reagents that operate through diazo or azide transfer mechanisms to convert amines to azides or functionalize molecules.
The retrieved papers consistently support the claim that sulfonyl azides function in diazo and azide transfer reactions. Papers [0], [10], and [11] all explicitly discuss or utilize sulfonyl azides in the context of diazo transfer and nitrogen transfer protocols. There are no papers contradicting this established chemical property.
