Rational syntheses of trisubstituted sulfur-bearing closo-boranes are presented. In the development of these syntheses unusual cationic closo-boranes 1,7,9-(Me(2)S)(3)-B(12)H(9) (3) and 1,2,10-(Me(2)S)(3)-B(10)H(7) (4) have been identified. These were initially recognized to be intermediates in the formation of the neutral trisubstituted species 1,7-(Me(2)S)(2)-9-(MeS)-B(12)H(9) (1) and 1,10-(Me(2)S)(2)-2-(MeS)-B(10)H(7) (2), respectively. Stable tetrafluoroborate salts were prepared and isolated, and their structures are presented. They are believed to represent the first structural determinations of cationic borane clusters of any type.
呈现了三取代含硫笼状硼烷的合理合成方法。在这些合成方法的发展过程中，发现了不寻常的阳离子笼状硼烷 1,7,9-(Me(2)S)(3)-B(12)H(9) (3) 和 1,2,10-(Me(2)S)(3)-B(10)H(7) (4)。这些阳离子最初被认为是中性三取代物种 1,7-(Me(2)S)(2)-9-(MeS)-B(12)H(9) (1) 和 1,10-(Me(2)S)(2)-2-(MeS)-B(10)H(7) (2) 形成的中间体。分别。制备并分离了稳定的四氟硼酸盐盐，并提出了它们的结构。它们被认为代表了任何类型的阳离子硼烷簇的第一个结构确定。
