Fluorophilicity switch by solvation.

A new type of fluorous distannoxanes, [XRf2SnOSnRf2Y]2 (Rf = C6F13C2H4; X, Y = C6F13SO3 (2) and (C6F13SO2)2N, Cl (3)) was prepared successfully as hydrates from the reaction of [ClRf2SnOSnRf2Cl]2 with C6F13SO3Ag and (C6F13SO2)2NAg, respectively. Despite their high fluorine content (59.85 and 59.

Organotin perfluorooctanesulfonates as air-stable Lewis acid catalysts: synthesis, characterization, and catalysis.

The reactions of 1,3-dichloro-1,1,3,3-tetrabutyldistannoxane and dialkyltin dihalides with silver perfluorooctanesulfonate provided the corresponding sulfonates as hydrates. The number of water molecules (n) of hydration was dependent on the conditions. The distannoxane derivative was identified as n from 0.
