Oxonium derivatives of closo-decaborate in reactions with sulfur-containing nucleophiles

Abstract

The reaction of the [B10H9O2C4H8]−, [B10H9OC4H8]−, and [B10H9OC5H10]− anions with negatively charged S-nucleophiles, such as SH−, SCN−, and S2O32−, resulted in the ring opening of the cyclic substituent and the formation of derivatives with the terminal thiol, thiocyanate, and thiosulfate groups. The structures of the products were confirmed by the IR, mass, and 1H, 11B, and 13C NMR spectra.
