Usage

Chemical Properties

Boron trifluoride acetonitrile complex is a colorless or light yellow transparent liquid, easily soluble in water, and miscible in various organic solvents such as alcohol and ether. It is mainly used as a catalyst for organic reactions. It is an important raw material for the preparation of boron halide, elemental boron, borane, sodium borohydride and other borides.

Synthesis

Boron trifluoride acetonitrile complex can be prepared by 20% oleum, boron anhydride and fluorite(9:1:3) were stirred at 130℃ and then poured into acetonitrile to give the complexation.

C6F5XeY Molecules (Y = F and Cl): New synthetic approaches. first structural proof of the organoxenon halide molecule C 6F5XeF

The arylxenonium salt [C6F5Xe][BF4] reacts with different sources of nucleophiles, Y (naked fluoride, [N(CH 3)4]F, the silanes, (CH3)3SiCl and (C2H5)3SiH, and the cadmiumorganyl, Cd(C 6F5)2), in coordinating solvents (C 2H5CN, CH3CN, CD3CN). While the products C6F5XeF, C6F5XeCl, and (C6F5)2Xe are well defined molecules, in reactions with (C2H5)3SiH only decomposition products presumably derived from 6F5XeH6F5XeC2H56F5XeF are discussed.

Anodic and cathodic reactions in acetonitrile/tetra-n-butylammonium tetrafluoroborate: an electrochemical and infrared spectroelectrochemical study

In situ infrared spectroelectrochemistry has been used to be observe electrolyte/solvent breakdown processes in TBAF/acetonitrile at a platinum electrode.Anodic breakdown gives the adduct CH3CNBF3 as the major product.Cathodic breakdown gives the anion of 3-aminocrotonitrile as the major product in the absence of water, and the formation of this product is a consequence of reduction of hydrogen dissolved in the metal.In the presence of water the anion of acetamide is also formed, and breakdown commences at much less negative potentials.
