EXPERIMENTAL .DETAILSThe preparation of VO(acac)2 was based on a known
procedure1 and modified to use VOSO4 as the starting material
(Scheme 2). The synthesis involved dissolving VOSO4 in water,
adding 2,4-pentanedione, and then adding an appropriate base.
We used saturated Na2CO3 solution and students continued to
add this solution until there was no effervescence upon further
addition. The solid product was filtered off and washed with
water. The solid was allowed to dry on the filter before being collected and stored in a sealed sample vial. The product was
characterized by infrared (IR) spectroscopy
