Diethylaminotitanium trichloride
Synonym: Titanium trichloride diethylamide, Trichloro(diethylamino)titanium (IV), TiCl3(NEt2)
CAS Number 684-55-9 | EC Number 810-139-6
Diethylaminotitanium trichloride, also known as Titanium trichloride diethylamide or Trichloro(diethylamino)titanium (IV), is a titanium-based organometallic compound with the molecular formula C₄H₁₀NTiCl₃ and a molecular weight of 226.35 g/mol. This compound crystallizes in green form and incorporates titanium in the +4 oxidation state, coordinated with three chloride ions and a diethylamino ligand. This configuration makes it highly reactive, especially in applications requiring a titanium source with strong electrophilic properties. Given its air and moisture sensitivity, it must be handled in an inert atmosphere and stored in a tightly sealed container to avoid hydrolysis.
Applications in Organic Synthesis and Catalysis
Diethylaminotitanium trichloride serves as a versatile reagent and catalyst in organic and organometallic synthesis, particularly in reactions where titanium’s strong electrophilic nature facilitates bond formation. It is frequently employed in alkylation and chlorination reactions, where its reactivity supports selective transformation of organic compounds. Its unique structure also enables its use in the preparation of other titanium complexes, making it valuable for advanced material synthesis in both research and industrial settings.
Storage and Handling Precautions
Due to its reactivity with water and air, diethylaminotitanium trichloride should be stored in a moisture-free environment and handled with caution to avoid decomposition. This compound requires storage under an inert gas, and users should wear protective gloves, eye protection, and ensure proper ventilation during handling. It is classified with hazard codes H261-3 (releases flammable gas upon contact with water), H314 (causes severe skin burns), H318 (causes serious eye damage), and H335 (may cause respiratory irritation), necessitating appropriate safety precautions.
Industrial and Laboratory Applications
In both laboratory and industrial settings, diethylaminotitanium trichloride is integral to the development of titanium-containing materials and catalysts. Its role in organic and inorganic synthesis extends to material science, where it contributes to the formation of thin films and coatings through vapor-phase deposition techniques. Additionally, its utility in producing highly reactive titanium intermediates makes it essential in fields focusing on fine chemicals and advanced material production.
Diethylaminotitanium trichloride was applied for the ALD growth of TiN thin films. The films grown using halide amino metal precursors contained lower concentrations of Cl in the film compared to TiN layers deposited with TiCl4. Additional testing revealed a potential preference for TiCl3(NEt2), which is more thermally stable and has reasonable vapor pressure ~0.28 Torr/ 75° C, with TiCl3(NMe2). See link below
