The products of reaction of fluorosilicic acid (FSA) with organic bases, the fluorosilicates of the relevant "onium" cations, find an application as anti-caries agents, ionic liquids, reagents for modified zeolite catalytic ...

The preparation and characterization of three isomeric carboxypyridinium and carboxyquinolinium hexafluorosilicate salts is described. The salts of the general formulas (LH)2[SiF6] (I–III, L = 2-carboxypyridine, ...

Pyridinium hexafluorosilicates with the compositions (LH)2[SiF6] (where L = 2,6-bis(hydroxymethyl)-pyridine (I), 4,5-bis(hydroxymethyl)-2-methylpyridine-3-ol (II)), monohydrate (LH)2[SiF6]H2O (L = 2-bromo-6-methylpyridine ...

Hexafluorosilicate with the composition (LH)2SiF6 (I), (L = 4-hydroxymethylpyridine) is isolated as the interaction product of an L methanol solution and 45% hydrofluorosilicic acid (L:H2SiF6 = 1:3). In the crystal structure ...

A tetraazacyclic ligand, tetrabenzylcyclen (L), was synthesized using an improved method with a higher yield by treatment of cyclen with benzylchloride in the presence of potassium carbonate. The reaction of L with an ...
