| [reaction suitability]
core: tin | [Synthesis]
Tetravinyltin is synthesized by the reaction of Vinylmagnesium Bromide with Tin(IV) Chloride in THF.1
| [Purification Methods]
Commercial tetravinyltin is commonly used without further purification. Large quantities are purified by fractional distillation. Smaller amounts may be filtered through a plug of silica.
| [Precautions]
Tetravinyltin is toxic and should only be used in a well ventilated hood. All glassware should be rinsed in a KOH/EtOH bath during cleaning.
