Open publisher page 47 citations

Abstract

The borane dimethyl sulfide adduct H 3 B·SMe 2 and the diethyl ether adduct of tris(pentafluorophenyl)borane, (C 6 F 5 ) 3 B·OEt 2, undergo facile exchange of hydride and pentafluorophenyl ligands, yielding (C 6 F 5 ) 2 HB·SMe 2 ( 1 ) and (C 6 F 5 )H 2 B·SMe 2 ( 2 ) depending upon the ratio of reagents used. In the presence of excess dimethyl sulfide, both compounds can be isolated as colorless crystals, which have been structurally characterized.
