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 ...

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 ...

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.

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 ...
s. They are also used in
organic synthesis
Organic synthesis is a special branch of chemical synthesis and is concerned with the intentional construction of organic compounds. Organic molecules are often more complex than inorganic compounds, and their synthesis has developed into one o ...
