METHOD FOR INHIBITING THE OXIDATION OF VO(ACAC)2 IN SOLUTION

The present invention provides a method to effectively inhibit the oxidization of VO(acac)in solution for months. It is believed that VO(acac)forms a π-complex with as many as three allylic alcohols which precludes reaction with any oxygen in the system.
