The Uses of Diaminomaleonitrile

Diaminomaleonitrile is a reagent used for the synthesis of 1,4-diazepine-2,3-dicarbonitrile dervatives. Also, it is used for the synthesis of Diaminomaleonitrile-based Schiff bases with a donor-acceptor structure and an aggregation-enhanced emission feature.

Preparation

Diaminomaleonitrile is obtained by tetramerization of hydrocyanic acid in the presence of catalysts such as alkylaluminum compounds.
