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.
