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,{{ cite web | url=http://www.inchem.org/documents/cicads/cicads/cicad13.htm | title=Concise International Chemical Assessment Document 13: Triphenyltin Compounds | publisher=International Programme on Chemical Safety | accessdate=2010-04-08 }} and both these classes of compounds are of local (but not global) environmental concern because they are persistent organic pollutants.{{ cite web | url=http://www.environment-agency.gov.uk/business/topics/pollution/39163.aspx | title=Triphenyltin compounds | publisher=Environment Agency | accessdate=2010-04-08 | url-status=dead | archiveurl=http://webarchive.nationalarchives.gov.uk/20100408055631/http%3A//www.environment%2Dagency.gov.uk/business/topics/pollution/39163.aspx | archivedate=2010-04-08 }} They are also used in organic synthesis to generate radicals or cleave carbon-oxygen bonds.{{ cite book | title = e-EROS Encyclopedia of Reagents for Organic Synthesis | chapter = Triphenylstannane | first = D.
