The reaction of indium(I) bromide with alpha,omega-alkanediylbis(bromo
mercury) complexes (alkane = butane, pentane, and hexane) resulted in
formation of the corresponding alpha,omega-alkanediylbis(dibromoindium
) compounds, which were isolated as THF adducts. The THF molecules of
the complexes are easily displaced Ey bromide anions, thus affording t
he corresponding alpha,omega-alkanediylbis(tribromoindate) dianions.
