Triphenyltin compounds are

organotin compounds Organotin compounds or stannanes are chemical compounds based on tin with hydrocarbon substituents. Organotin chemistry is part of the wider field of organometallic chemistry. The first organotin compound was diethyltin diiodide (), discovered by ...

with the general formula (C₆H₅)₃SnX. They contain the triphenyltin group, (C₆H₅)₃Sn, or Ph₃Sn, which consists of an atom of

tin Tin is a chemical element with the symbol Sn (from la, stannum) and atomic number 50. Tin is a silvery-coloured metal. Tin is soft enough to be cut with little force and a bar of tin can be bent by hand with little effort. When bent, t ...

phenyl group In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6 H5, and is often represented by the symbol Ph. Phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen ...

s. Examples of triphenyltins include: *

Triphenyltin hydride Triphenyltin hydride is the organotin compound with the formula (C6H5)3SnH. It is a white distillable oil that is soluble in organic solvents. It is often used as a source of "H·" to generate radicals or cleave carbon-oxygen bonds. Preparati ...

Triphenyltin chloride Triphenyltin chloride is an organotin compound with formula Sn(C6H5)3Cl. It is a colourless solid that dissolves in organic solvents. It slowly reacts with water. The main use for this compound is as a fungicide and antifoulant. Triphenyl ti ...

, Ph₃SnCl * Triphenyltin acetate, Ph₃SnOAc Triphenyltin compounds have been used extensively as algicides and molluscicides in antifouling products since the 1960s, together with tributyltin compounds, and both these classes of compounds are of local (but not global) environmental concern because they are

persistent organic pollutant Persistent organic pollutants (POPs), sometimes known as "forever chemicals", are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. They are toxic chemicals that adversely ...
