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.
