Tetrakis(dimethylamino)tin Chemical Properties, Uses, Production

Preparation

TETRAKIS(DIMETHYLAMINO)TIN can be prepared by the following steps:

(1) Adding a solvent to a metal hydride to obtain a suspension;

(2) Adding anhydrous tin tetrachloride dropwise to the suspension and reacting to obtain a reaction solution;

(3) Passing dimethylamine into the reaction solution and stirring to obtain a mixture;

(4) Subjecting the mixture to reduced pressure to remove low-boiling point, reduced pressure distillation, and rectification to obtain the TETRAKIS(DIMETHYLAMINO)TIN.

Uses

ALD precursor for tin

Chemical Properties

clear fuming liquid

General Description
