Anhydrous SnCl 2 is prepared by the action of dry hydrogen chloride gas on tin metal. The dihydrate is made by a similar reaction, using hydrochloric acid: Sn (s) + 2 HCl (aq) → SnCl 2 (aq) + H 2 (g) The water then carefully evaporated from the acidic solution to produce crystals of SnCl 2 ·2H 2 O.
Stephen aldehyde synthesis, a named reaction in chemistry, was invented by Henry Stephen (OBE/MBE).This reaction involves the preparation of aldehydes (R-CHO) from nitriles (R-CN) using tin(II) chloride (SnCl 2), hydrochloric acid (HCl) and quenching the resulting iminium salt ([R-CH=NH 2] + Cl −) with water (H 2 O).

Tin(IV) chloride is well known as a Lewis acid. Thus it forms hydrates. The pentahydrate SnCl 4 ·5H 2 O was formerly known as butter of tin. They all consist of [SnCl 4 (H 2 O) 2] molecules together with varying amounts of water of crystallization. The additional water molecules link together the molecules of [SnCl 4 (H 2 O) 2] through ...
