Additionally, SnCl 2 is used to selectively reduce aromatic nitro groups to anilines. [11] Aromatic nitro group reduction using SnCl 2. SnCl 2 also reduces quinones to hydroquinones. Stannous chloride is also added as a food additive with E number E512 to some canned and bottled foods, where it serves as a color-retention agent and antioxidant.
The additional water molecules link together the molecules of [SnCl 4 (H 2 O) 2] through hydrogen bonds. [3] Although the pentahydrate is the most common hydrate, lower hydrates have also been characterised. [4] Aside from water, other Lewis bases form adducts with SnCl 4. These include ammonia and organophosphines.
From a chemical formula: This is a redirect from a chemical/molecular formula to its systematic (technical) or trivial name.
Nitrous acid (molecular formula H N O 2) is a weak and monoprotic acid known only in solution, in the gas phase, and in the form of nitrite (NO − 2) salts. [3] It was discovered by Carl Wilhelm Scheele, who called it "phlogisticated acid of niter". Nitrous acid is used to make diazonium salts from amines.
3 R 4 Sn + SnCl 4 → 4 R 3 SnCl R 4 Sn + SnCl 4 → 2 R 2 SnCl 2 R 4 Sn + 3 SnCl 4 → 4 RSnCl 3. A related method involves redistribution of tin halides with organoaluminium compounds. [2]: 45–47 In principle, alkyltin halides can be formed from direct insertion of the metal into the carbon-halogen bond.
Tributyltin chloride is an organotin compound with the formula (C 4 H 9) 3 SnCl. It is a colorless liquid that is soluble in organic solvents. It is a colorless liquid that is soluble in organic solvents.

Trimethyltin chloride can be prepared by the redistribution reaction of tetramethyltin with tin tetrachloride. [3]SnCl 4 + 3 Sn(CH 3) 4 → 4 (CH 3) 3 SnCl. This redistribution reaction is typically performed with no solvent because high temperatures are required and purification is simplified.
