Tributyltin chloride is an organotin compound with the formula (C4H9)3SnCl. It is a colorless liquid that is soluble in organic solvents.

Preparation and reactions

[edit]

The compound is prepared by a redistribution reaction by combining stannic chloride and tetrabutyltin:

3 (C4H9)4Sn + SnCl4 → 4 (C4H9)3SnCl

Tributyltin chloride hydrolyzes to the oxide [(C4H9)3Sn]2O

Tributyltin chloride is used as a precursor to other organotin compounds[1] and reagents, such as tributyltin hydride.
