Abstract

Benzenesulfonamides represent a hydrogen donor‐acceptor moiety that is changed to a bisacceptor by deprotonation. The dimerization constant of N‐tosyl‐n‐butylamine (7) and N‐tosyl‐L‐alanine (9‐H) in CDCl~3~ and the binding constant of the tetrabutylammonium salt 7·NBu~4~ to urea in DMSO were determined by ^1^H‐NMR titration methods. The X‐ray structure analysis of 9‐H is reported.
