摘要: [7646-78-8] Cl4Sn (MW 260.51) InChI = 1/4ClH.Sn/h4*1H;/q;;;;+4/p-4/f4Cl.Sn/h4*1h;/q4*-1;m InChIKey = HPGGPRDJHPYFRM-LUCXXLOKCB (strong Lewis acid used to promote nucleophilic additions, pericyclic reactions, and cationic rearrangements; chlorination reagent) Alternate Name: stannic chloride. Physical Data: colorless liquid; mp −33 °C; bp 114.1 °C; d 2.226 g cm−3. Solubility: reacts violently with water; sol cold H2O; dec hot alcohol, Et2O, CCl4, benzene, toluene, acetone. Form Supplied in: colorless 1 M soln in CH2Cl2 or heptane; widely available. Purity: reflux mercury P2O5 for several hours, then distill under reduced nitrogen pressure into receiver P2O5. Redistill. Typical impurities: hydrates. Handling, Storage, Precautions: hygroscopic; should be stored a glove box over minimize exposure moisture. Containers flushed N2 Ar tightly sealed. Perform all manipulations Ar. Solvating H2O liberates much heat. Use fume hood.
