Synthesis
This compound can be obtained by reacting indium(III) chloride with a diethyl ether solution of ethyl magnesium chloride:
- InCl
3 + 3 C
2H
5MgCl → In(C2H5)3 + 3 MgCl
2
Other routes are also known.[3]
Properties
Indium triethyl is a colorless, toxic, oxidation and hydrolysis-sensitive liquid. It is a monomer in the gaseous and dissolved state. The compound reacts with halomethanes to form diethyl indium halides.[4]
Triethylindium is highly reactive with water:
- In(C2H5)3 + H
2O → In(C2H5)2OH + C
2H
6↑
Applications
Indium triethyl is used to prepare indium phosphide layers for microelectronics.[5]
