Reduction of BH3.THF by Alkali Metal (K, Rb, Cs) and Ytterbium Mercury Amalgams

摘要

The octahydrotriborate(1-) ion, (B3H8)-, is employed in a wide variety ofapplications: syntheses of novel metallaborane, higher borane, heteroatom borane, and carborane cluster compounds, the reduction of a wide variety of organic compounds, the preparation of electrode coatings through reduction reactions, applications to explosive and propellant technology, neutron capture therapy, and serum triglyceride and serum cholesterol biological studies. A number of procedures have been reported for the preparation of (B3H8)-salts. Of these, the most common starting points involve the reaction of sodium borohydride with boron trifluoride etherate or the reaction of sodium borohydride with iodine.
