ArN2BF4(Ar=Ph，p-Tol，p-ClC6H4)在SO2，H-2和Pd/C的催化量下，在室温下转化为相应的亚磺酸(ArSO2H)。分离的产率分别为：PhSO2H：84%(4h)，p-TolSO(2)H：84%(2 H)，pClc(6)H(4)SO(2)H：93%(4 H)。(C)1999 Elsevier Science B.V.保留所有权利。
ArN2BF4 (Ar = Ph, p-Tol, p-ClC6H4) are converted into the corresponding sulfinic acids (ArSO2H) in the presence of SO2, H-2 and catalytic amounts of Pd/C at room temperature. The isolated yields are: PhSO2H: 84% (4 h); p-TolSO(2)H: 84% (2 h) and pClC(6)H(4)SO(2)H: 93% (4 h). (C) 1999 Elsevier Science B.V. All rights reserved.
