Description

General description

Nonafluorobutane-1-sulfonic acid is a colorless liquid that can be considered as a superacid, which can be synthesized by reacting 1-iodononafluorobutane with sodium dithionite in the presence of sodium bicarbonate in acetonitrile/water.

Application

Nonafluorobutane-1-sulfonic acid may be used as catalyst in the synthesis of 6-chloro-6H-dibenz[c,e][1,2]oxaphosphorin and N-benzylpyridin-2-amine.
