Conclusions
-
1.
Hexafluoroacetone benzenesulfonylimine reacts unambiguously with dimethylformamide, dimethylacetamide, and N-methylpyrrolidone to give the corresponding N-benzenesulfonylamidines and hexafluoroacetone.
-
2.
2-Hydroxypyridine reacts with hexafluoroacetone benzenesulfonylimine the same as tertiary carboxylic acid amides to give 2-benzenesulfonylaminopyridine.
-
3.
Some rules were ascertained for the transformation that take place in a system composed of hexafluoroacetone benzenesulfonylimine and carboxamides, and some theories were expressed regarding the mechanism of this reaction.
