Reaction-controlled phase-transfer catalytic oxidative cleavage of cyclopentene to glutaraldehyde over peroxy-niobic acid
The oxidative cleavage of cyclopentene to glutaraldehyde with aqueous H.,02 was performed over a peroxy-niobic acid catalyst with high yield (72%) and complete conversion of cyclopentene under mild reaction conditions. Peroxy-niobic acid has been shown as a "reaction-controlled phase-transfer" catalyst, which has the advantages of both homogeneous and heterogeneous catalysts.
