A facile catalyst-free sulfonylation of phenoxazine with sulfonyl hydrazides was efficiently developed in HO/HFIP without any catalyst. This metal- and catalyst-free protocol is suitable for aromatic and aliphatic reagents to afford the corresponding sulfones in moderate to high yields. A gram-scale experiment was performed to assess the practicability of the method.
在无任何催化剂的情况下，吩噁嗪与磺酰肼在HO/HFIP中高效地实现了简便的无催化剂磺酰化反应。这种无金属和无催化剂的方法适用于芳香族和脂肪族试剂，能以中等到高的产率得到相应的砜。进行了克级实验以评估该方法的实用性。
