A novel catalyst-free sulfonation reaction for synthesizing 3-sulfone nitrile compounds from sulfonyl hydrazides and acrylonitriles in water, without any metal catalyst, ligand or organic solvent, was demonstrated. This catalyst-free protocol provides a new synthetic method for the construction of 3-sulfone nitrile compounds with excellent yields. The D2O experiment adequately proved that the catalyst-free
展示了一种新型的无催化剂磺化反应,该反应无需任何金属催化剂,配体或有机溶剂即可从水中的磺酰肼和丙烯腈合成3-砜腈化合物。该无催化剂方案为3-砜腈化合物的优异产率提供了一种新的合成方法。D 2 O实验充分证明了无催化剂的磺化反应是通过迈克尔加成机理发生的,并且3-砜腈的氢来自水。
