Tributyltin azide

Tributyltin azide is a heterocyclic organic compound that is used in organic synthesis. It has shown antihypertensive activity and the ability to inhibit fatty acid synthesis. Tributyltin azide has also been shown to have biological properties, such as the coordination of proteins and enzymes.

Tributylstannanylium Azide is used in preparation method of Polycaprolactone-based Polyamide composite material.

A cooled solution of sodium azide (4.10 g, 63.0 mmol) in water (13 mt) at 8°C BusSnCI (17 1 ml) is added dropwise while stirring the solution. After 2h of stirring at 8°C, dichloromethane (38 mi) is added, stirred for another 5 minutes, and phases separated. The water phase is washed with dichloromethane (13 ml). Combined organic phases are washed with 10% NaCI (13 ml) and distilled water (13 ml). The organic phase is dried with sodium sulfate (6.34 g), and the solvent is removed under reduced pressure to give the oily product Tributyltin azide (19.2 g, 91.8%).

Organotin derivatives are known to be toxic. Avoid inhalation and contact with skin. Organotin azides are claimed to be thermally very stable. However, extreme caution should be exercised when heating an azide solution due to the possibility of explosion. Use in a fume hood.
