Hexamethylditin, also known as Hexamethyldistannane or Trimethyltin dimer, is an organotin compound with the molecular formula C₆H₁₈Sn₂ and a molecular weight of 327.63 g/mol. Structurally, it consists of two tin atoms in a Sn-Sn bond, each coordinated to three methyl groups, providing stability to this compound. This colorless liquid to solid has a purity of 99% as verified by gas chromatography and is highly sensitive to air and moisture, requiring storage in a cool, dry environment.
Hexamethyldistannane serves as a key reagent in organotin chemistry, often used for introducing tin into organic molecules. Its structure allows for controlled reactivity in applications such as polymer synthesis, where it facilitates various organometallic transformations.
This compound is highly toxic and flammable, with hazard codes H227, H300, H310, H330, H400, and H410. Proper handling includes the use of gloves, goggles, and respiratory protection. Due to its moisture sensitivity, it should be stored in tightly sealed containers at low temperatures.
Hexamethylditin is essential in materials science and synthesis, where its organotin properties support applications in advanced material development. It is commonly used in specialized synthesis and catalysis for creating high-performance materials in both research and industrial settings.
Hexamethylditin is used to prepare aryl tin compounds for microwave-assisted Stille cross-coupling with halopyridines or copper-mediated O-arylation of phenols. The synthesis of this product is described in the literature. See links below
