Fluorosulfonic anhydride: a potential fluorosulfonating agent

Abstract

Reactions of pyrosulfuryl fluoride, S2O5F2, with various inorganic substrates are carried out to explore its potential and usefulness as a fluorosulfonating agent. New fluorosulfonates, viz; [Formula: see text], [Formula: see text] NaBiO(SO3F)2, and Ti(OCH3)2(SO3F)2 have been prepared by reacting [Formula: see text], [Formula: see text] NaBi(CF3COO)4, and Ti(OCH3)4, respectively, with S2O5F2. These compounds have been characterized by elemental analyses and infrared and 19F nmr spectra. Keywords: new fluorosulfonates, [Formula: see text], [Formula: see text] NaBiO(SO3F)2, Ti-(OCH3)2(SO3F)2.
