N-Substituted sulfenamoylbenzoates were synthesized by transamination of N-unsubstituted sulfenamoylbenzoates with amines. The reaction did not always proceed by simple amine exchange between the amines and ammonia on thesulfur atom of the sulfenamides. In reactions with aliphatic amines, the sulfenamides cyclized to form N-substituted1,2-benzisothiazolin-3-ones. The synthesis of 1,2-benzisothiazolin-3-ones
