ABSTRACT:
A method is disclosed for the production of dialkyl-tin-dichlorides whose alkyl groups have 1 to 22 carbon atoms. Trialkyl-aluminum is slowly added to a solution of tin-diacetate-dichloride and tetrahydrofuran in the mole ratio of about 2:3. The aluminum-triacetate precipitating during the reaction is removed by filtration and the tetrahydrofuran used as solvent is removed by distillation.
