We present evidence that the reaction of anilines with ArCH2SO2Cl and ArCH2SO2F goes mainly via the sulfene (ArCHSO2) and is not a simple nucleophilic displacement at sulfur, as was assumed in the above paper by I. Lee and R.K. Kang (Tetrahedron Lett. 28, 1183 (1987)), and hence that their conclusions about the interpretation of ϱ and ϱXY values are unfounded.
我们目前的证据,与拱苯胺的反应2 SO 2 Cl和ARCH 2 SO 2 ˚F主要变为经由亚磺酰(ArCHSO 2),而不是在硫简单的亲核置换,如假定在上述纸张通过我。Lee和RK康(四面体通讯28,1183(1987)),因此,他们的约ρ和ρ的解释结论XY值是没有根据的。
