Tetraethyltin is a colourless flammable liquid, soluble in diethyl ether and insoluble in water, that freezes at −112 °C and boils at 181 °C.[1][2] It is used in the electronics industry.
Tetraethyltin can be obtained by reacting ethylmagnesium bromide with tin(IV) chloride:[1]
- SnCl4 + 4 CH3CH2MgBr → (CH3CH2)4Sn + 4 MgBrCl
The same reaction can be used to obtain tetra-n-propyltin and tetra-n-butyltin.[1]
Tetraethyltin is converted in the body to the more toxic triethyltin.[3][clarification needed]
