The inexpensive room temperature ionic liquid (RTIL), [bmim][Br] has been found to be a superior medium for the Bi-mediated Barbier-type allylation of aldehydes compared to other conventional solvents. It plays the dual role of a solvent and a metal activator enabling higher yields of the products in a shorter reaction time using stoichiometric/near-stoichiometric amounts of reagents. Plausibly, [bmim][Br] activates Bi metal by a charge transfer mechanism. The 1H VT-NMR studies suggested that both the allylating species, allylbismuth dibromide and diallylbismuth bromide, are generated in situ.

A spectrophotometric study of the Cu(II) – acetone – hydrochloric (hydrobromic) acid systems has revealed that at relatively high ratios of halide: copper there is a probable equilibrium between four-, five-, and six-coordinate halogenocopper(II) complexes. A distorted tetrahedral species is favored at the highest ratios. Ligand field bands of pseudo-octahedral monohalogenocopper(II) complexes and, in the visible region, a charge transfer band of the six-coordinate complex, [CuCl4(ac)2]2−, have been identified. The results of the present work point to the important role of the solvent in determining the geometries and absorption spectra of the complexes, a factor that seems to have been misinterpreted by some previous workers.
