Syntheses and chemistry of bis- and tris-mercaptoborates

Abstract

The preparation and chemistry of bis- and tris-mercaptoborates based on closo-E12 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 of the third dimethylsulfide substituent to the closo-boranes is thought to proceed via an unusual cationic intermediate. © 2006 IUPAC.
