Tetrakis(dimethylamino)diboron

[1630-79-1] C8H24B2N4 (MW 197.93) InChI = 1S/C8H24B2N4/c1-11(2)9(12(3)4)10(13(5)6)14(7)8/h1-8H3 InChIKey = KMCDRSZVZMXKRL-UHFFFAOYSA-N (reagent used to synthesize other diboron species) Physical Data: flammable. boiling point: 55–57 C. Analysis of Reagent Purity: 11B (Δ = 36 ppm) and 1H NMR (Δ = 2.76 ppm). Preparative Methods: Wurtz coupling with molten sodium in toluene.1 Form Supplied in: colorless to yellow liquid. Available commercially. Purification: Fractional distillation (90°C, 12 Torr). Handling, Storage and Precantions: sensitive to air and moisture. Use under inert atmosphere in a fume hood using standard Schlenk techniques. Chemist should be appropriately protected with gloves, goggles, and lab coat. Keep away from sources of ignition. Storage in a sealed vessel at or below 70°C. Storage at 0°C also possible but requires vessel to warm to ambient temperature in a fume hood before opening under N2.
