Hydroesterification of tert-butyl alcohol with ethanol catalyzed by transition metal triphenylphosphine complexes was first investigated in room temperature ionic liquids. Compared with organic solvents, ionic liquids show unexpected product selectivity and reach higher conversion. The products can easily be separated from the ionic liquids by decantation due to their immiscibility with the ionic liquids. A possible reaction route is also proposed.
