Zinc bis(trifluoromethylsulfonyl)imide(CAS: 168106-25-0)

Zinc bis(trifluoromethylsulfonyl)imide (CAS: 168106-25-0) is a white to off-white crystalline solid with a molecular weight of approximately 345.2 g/mol. It is soluble in common organic solvents like dimethylformamide (DMF) and dimethyl sulfoxide (DMSO). Chemically, it is a strong Lewis base and a good ligand for transition metals. It has low reactivity under normal conditions but can decompose at high temperatures and in the presence of moisture.

Zinc bis(trifluoromethylsulfonyl)imide is typically synthesized by treating zinc oxide with triflic anhydride in the presence of a Lewis acid catalyst such as aluminum chloride. The reaction is carried out in a polar aprotic solvent like tetrahydrofuran (THF). The product is isolated by filtration and recrystallization, providing a pure crystalline form with high yield and selectivity.

Zinc bis(trifluoromethylsulfonyl)imide (CAS: 168106-25-0) is used in various industries including pharmaceuticals for synthesis of certain organic compounds, polymers as a stabilizer, sensors for detecting specific gases, and semiconductors as a dopant. Its unique properties make it valuable in these applications.

When handling Zinc bis(trifluoromethylsulfonyl)imide (CAS: 168106-25-0), it is essential to wear appropriate personal protective equipment (PPE) such as gloves and safety glasses. Work should be conducted in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up carefully using appropriate absorbents. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
