Abstract

The heterobinuclear derivatives of arsenic(III) and boron of the general formula [(RO)2P(S)S]2As(μ -OPri)2B(OPri)2 where R = Me(1); Et (2); Pri (3); Prn (4); and Bun (5)] have been synthesized by the reactions of chlorobis(dialkyldithiophosphato)arsenic (III) compounds, [(RO)2P(S)S]2AsCl with sodium tetraisopropoxoborate, NaB(OPri)4 in 1:1 molar ratio in refluxing benzene solution. All these new nonvolatile, moisture-sensitive, light-yellow colored, viscous liquid derivatives have been characterized by elemental analyses and molecular weight measurements. Their FT IR, multinuclear NMR (1H, 13C, 31P, and 11B), and FAB mass spectral studies have been discussed.
