Cu-MOF: an efficient heterogeneous catalyst for the synthesis of symmetric anhydrides via the C-H bond activation of aldehydes

摘要

In this paper, an efficient and straightforward synthetic approach for the preparation of a number of symmetric carboxylic anhydrides was reported using Cu-2(BDC)(2)(DABCO) as an efficient heterogeneous catalyst via the C-H bond activation of aldehydes with excellent yields and simple work up. This C-H bond activation reaction appears simple and convenient, has a wide substrate scope and makes use of cheap, abundant, and easily available reagents. The Cu-MOF catalyst was recycled and reused four times without any Loss of catalytic activity.
