Determination of pKa values of fluoroalkanesulfonamides and investigation of their nucleophilicity
摘要:
The pK(a) values of a series of fluoroalkanesulfonylamides were measured by potentiometric titration. Different kinds of alkyl halides and tosylates were employed to investigate the nucleophilicity of fluoroalkanesulfonylamides. Fluoroalkanesulfonylamides with longer fluoroalkyl chain have weaker nucleophilicity. (C) 2010 Elsevier B.V. All rights reserved,
