Lewis acidic ionic liquids were used to catalyze the reaction of epoxypropane with POCl3. Considering the lower cost and catalytic activities, we concluded that [Et3NH]Cl/AlCl3 was the most attractive ionic liquid from an economical point of view. But it would be easily inactivated because of sensitive to water and air. Moreover, it could not be reused easily because of difficulty recovery in the reaction. However, supporting [Et3NH]Cl/AlCl3 catalyst could resolve above problems. Supporting [Et3NH]Cl/AlCl3 catalyst could be separated by filter easily and reused 5 times in 98% yield. Furthermore, the catalyst was applicable to other epoxy ether cleaving reactions.

The chelates of the type M2 have been prepared by the solvolysis of the corresponding divalent metal chlorides or acetate by respective trialkylphosphates.While the cobalt(II) derivatives are tetrahedral with two (RO)2P(O)2 chelating groups, the nickel(II) derivatives have a distorted octahedral geometry resulting from the possible participation of the ethereal oxygen of the alkoxy group.The organophosphate chelating groups reveal 'antispectrochemical behaviour' in these systems.
