Tetra-n-butyltin is used in hydrogenolysis reactions and as a transition metal catalyst. It is also used stabilizers in the manufacture of polyvinyl chloride. | [Flammability and Explosibility]
Notclassified | [Purification Methods]
Dissolve it in Et2O, dry it over MgSO4, filter, evaporate and distil it under reduced pressure. Although it does not crystallise easily, once the melt has crystallised, then it will recrystallise more easily. It is soluble in Et2O, Me2CO, EtOAc and EtOH but insoluble in MeOH and H2O, and shows no apparent reaction with H2O.
