Chlorotriphenyltin

The Uses of Chlorotriphenyltin

Chlorotriphenylstannane is used in the synthesis of nanoparticles which bear triamide ligands.

The Uses of Chlorotriphenyltin

Triphenyltin chloride is an important organic intermediate. It is used in agrochemical, pharmaceutical and dyestuff field.

Definition

ChEBI: An organotin compound that is triphenylstannane in which the hydrogen attached to tin is replaced by a chloro group. A fungicide used to control blights on potatoes, leaf spot diseases on sugar beet and anthracnose on beans.

General Description

White crystalline solid, insoluble in water; soluble in organic solvents. Used as a rodent repellent, molluscicide, fungicide and insecticide.

Air & Water Reactions

Hydrolyzes to hydroxide in water.

Reactivity Profile

Chlorotriphenyltin is in the family of tin compounds widely used as stabilizers for plastics, additives to paint(as antifouling agents). Some have catalytic properties. Examples include butyl tin, dibutyl tin oxide. Their main hazard is associated with their high toxicity, in skin adsorption or inhalation.

Health Hazard

Toxic and irritating to the skin. Dermal exposure may lead to severe skin burns as well as renal failure and possible death. (Non-Specific -- Tin Compounds, Organic) Target organs affected are central nervous system, eyes, liver, urinary tract, skin and the blood.

Fire Hazard

When heated to decomposition, Chlorotriphenyltin emits toxic fumes of chlorides. Hydrolyzes to hydroxide in water. Stable when stored in dark with dry air.

Safety Profile

Poison by ingestion, intraperitoneal, and intravenous routes. Experimental reproductive effects. Mutation data reported. An insect chemosterilant. See also TIN COMPOUNDS. When heated to decomposition it emits toxic fumes of Cl-.

Purification Methods

Purify it by distillation, followed by recrystallisation from MeOH by adding pet ether (b 30-60o), m 105-106o [Kozeschow et al. Chem Ber 67 1348 1934], or by crystallisation from Et2O, or 5 parts of EtOH and a small volume of pet ether. [Krause Chem Ber 51 914 1918.] It sublimes in a vacuum. [Beilstein 16 H 914, 16 I 540, 16 II 625, 16 III 1240, 16 IV 1606.] HIGHLY TOXIC.
