A recyclable, convenient, and efficientcatalytic system for C-acylation of 1,3-dicarbonyl compounds and malononitrile with acid chlorides has been developed, giving moderate to excellent yields under mild conditions. This is the firstcatalytic example of such reactions. In addition, by applying this protocol as the key step, 3,5-disubstituted-1H-pyrazole-4-carboxylate can easily be synthesized in
