Triphenyltin compounds

Triphenyltin compounds are organotin compounds with the general formula (C₆H₅)₃SnX. They contain the triphenyltin group, (C₆H₅)₃Sn, or Ph₃Sn, which consists of an atom of tin bonded to three phenyl groups. Examples of triphenyltins include:

• Triphenyltin hydride, Ph₃SnH
• Triphenyltin hydroxide, Ph₃SnOH
• Triphenyltin chloride, Ph₃SnCl
• Triphenyltin acetate, Ph₃SnOAc

Triphenyltin compounds have been used extensively as algicides and molluscicides in antifouling products since the 1960s, together with tributyltin compounds,^[1] and both these classes of compounds are of local (but not global) environmental concern because they are persistent organic pollutants.^[2] They are also used in organic synthesis to generate radicals or cleave carbon-oxygen bonds.^[3]
