Friedel-Crafts catalyst. | [Preparation]
Stannic fluoride can be prepared from the reaction of fluorine, chlorine trifluoride, or bromine trifluoride with tin(II) or tin(IV) compounds. It acts as a Lewis acid to form many complexes. It is used in the manufacture of glasses. | [Reactions]
Stannic fluoride combines with ammonia and other bases, and also with alkali and other fluorides to form stannifluorides of the type M2SnF6. Stannic fluoride forms with ammonia at 43° C. the white solid SnF4.NH3, which can be heated to 400° C. with loss of very little ammonia; the compound SnF4.2NH3 is formed when stannic fluoride and ammonia are heated in a sealed tube at 120°-130° C. Both compounds dissolve in water, but their solutions gradually decompose. Aniline, pyridine, and quinoline also form additive compounds with stannic fluoride. | [reaction suitability]
