Chloroaluminate(III) ionic liquid mediated synthesis of transition metal-cyclophane; complexes: their role as solvent and Lewis acid catalyst

摘要

The preparation of transition metal-cyclophane complexes using the ionic liquid system [bmim]Cl-AlCl_3 ([bmim]~+ = =1-butyl-3-methylimidazolium cation) as both the solvent and Lewis acid catalyst is described. Both known and novel complexes are prepared. Simple arene complexes of manganese have also been prepared in order to demonstrate the chemistry and there reactions are compared with the literature preparations conducted in conventional organic solvents.
