    Abstract: The invention provides new methods for synthesis of B 9 H 9 , B 10 H 10 2- , B 11 H 14 , and B 12 H 12 2- salts, particularly alkylammonium salts of B 9 H 9 , B 10 H 10 2- , B 11 H 14 , and B 12 H 12 2- . More particularly, the invention provides methods of preparing tetraalkylammonium salts of B 9 H 9 , B 10 H 10 2-, B 11 H 14 , and B 12 H 12 2- by pyrolysis of tetraalkylammonium borohydrides under controlled conditions. The invention additionally provides methods of preparing, in an atom efficient process, octadecaborane from the tetraalkylammonium salts of the invention. Preferred methods of the invention are suitable for preparation of isotopically enriched boranes, particularly isotopically enriched 10B 18 H 22 and 11 B 18 H 22 .

    Abstract translation: 本发明提供合成B9H9,B10H10 2-,B11H14和B12H12 2-的新的方法,特别是B9H9,B10H10 2-,B11H14和B12H12 2-的烷基铵盐。 更具体地,本发明提供了通过在受控条件下热解四烷基铵硼氢化物来制备B9H9,B10H10 2 - ,> B11H14,和B12H12 2-的四烷基铵盐的方法。 本发明另外提供了在原子有效方法中制备本发明的四烷基铵盐的十八硼烷的方法。 本发明的优选方法适用于制备同位素富集的硼烷,特别是同位素富集的10B18H22和B18H22。
