Publikováno v: Inorganic Chemistry. 51:2374-2380

Rational syntheses of trisubstituted sulfur-bearing closo-boranes are presented. In the development of these syntheses unusual cationic closo-boranes [1,7,9-(Me2S)3-B12H9]+ (3) and [1,2,10-(Me2S)3-B10H7]+ (4) have been identified. These were initiall

Syntheses and Chemistry of Bis- and Tris-mercaptoborates

Autor: Hoitung T. Leung, Teshome B Yisgedu, Sheldon G. Shore, Roman G. Kultyshev, Ewan J. M. Hamilton

Publikováno v: ChemInform. 37

The preparation and chemistry of bis- and tris-mercaptoborates based on closo-B12 and closo-B10 structures is described. These species undergo a number of reactions such as halogenation and alkylation without changing the closo-borane core. Addition
