| Abstract: | The following cesium tetrathienylborates were synthesized and screened for gravimetric reagent properties: tetrakis(2-thienyl), tetrakis(3-thienyl), tetrakis(5-bromo-2-thienyl), tetrakis(5-chloro-2-thienyl),tetrakis(2,5-dimethyl-3-thienyl), tetrakis(5-ethyl-2-thienyl), tetrakis(5-methyl-2-thienyl), and tetrakis(5-t-butyl-2-thienyl). Of these, the tetrakis(5- alkyl-2-thienyl) borates were not sufficiently stable for complete characterization. The following are possible reagents for cesium and quaternary ammonium cations: sodium tetrakis(2-thienyl), tetrakis(3-thienyl), and tetrakis(2,5-dimethyl-3-thienyl)borates. |
