• Chemical Classes: Toxic Gases & Vapors -> Corrosive Gases
• Canonical SMILES: B(Cl)(Cl)Cl
• Inhalation Risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Inhalation of this gas may cause lung oedema. Rapid evaporation of the liquid may cause frostbite. Exposure at high levels could cause death. The effects may be delayed. Medical observation is indicated.
• Description: Boron trichloride is a colorless, acid gas that fumes in the presence of moist air. It is packaged in steel cylinders as a liquid under its own vapor pressure of 19.1 psia (132 kPa, abs) at 70°F (21.1°C). It reacts with water or moist air to produce hydrochloric and boric acid.
• Uses: Boron trichloride is a Lewis acid, forming stable addition compounds with such donors as ammonia and the amines and is used in the laboratory to promote reactions that liberate these donors. The compound is important industrially as a source of pure boron (reduction with hydrogen) for the electronics industry. It is also used for the preparation of boranes by reaction with metal hydrides. manufacture of and purification of boron; as catalyst for organic reactions; in semiconductors; in bonding of iron, steels; in purification of metal alloys to remove oxides, nitrides and carbides. Boron trichloride is used in the refining of aluminum, copper, magnesium, and zinc to remove oxides, nitrides, and carbides trom the molten metal. Carbon monoxide, hydrogen, and nitrogen can be removed from an aluminum melt by treating with boron trichloride. It also improves the tensile strength of aluminum and will allow remelting without a major change in the grain structure. The electronic industry benefits trom boron trichloride in many applications. It is used in the production of optical fibers, as a p-type dopant for thermal diffusion in silicon, and for ion implantation.

Separating electrophilicity and lewis acidity: The synthesis, characterization, and electrochemistry of the electron deficient tris (aryl)boranes B(C₆F₅)_3-n(C₆Cl ₅)_n (n = 1-3)

10.1021/ja205037t

The research focuses on the synthesis, characterization, and electrochemical analysis of a new family of electron-deficient tris(aryl)boranes, B(C6F5)3n(C6Cl5)n (n = 13), which allows for an investigation into the steric and electronic effects resulting from the gradual replacement of C6F5 with C6Cl5 ligands. The experiments involved the use of various reactants such as C6Cl5Li, BCl3, CuC6F5, and Zn(C6Cl5)2, among others, to synthesize the target compounds through a series of metathesis reactions and halide metathesis reactions. The synthesized compounds were structurally characterized using single crystal X-ray diffraction, and their spectroscopic properties were analyzed using 11B, 19F, and 13C NMR. Additionally, density functional theory (DFT) calculations were performed to optimize the structures and compute 11B shielding constants. The electrochemical behavior of the compounds was investigated using cyclic voltammetry, and the stability of the radical anions was assessed through EPR spectroscopy. The analyses provided insights into the electron deficiency at the boron center, the structural changes upon ligand substitution, and the correlation between electronic effects and Lewis acidity.
