Preparation and reactions
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.
