Reference of 1187-42-4,Some common heterocyclic compound, 1187-42-4, name is Diaminomaleonitrile, molecular formula is C4H4N4, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: AlCl3 (15 molpercent) was added to a solution of DAMN (1 mmol), ketone (1 mmol) and isocyanide (1 mmol), in 5 ml of CH3CN. The resulting mixture was stirred for an appropriate time at room temperature. After completion of the reaction, as indicated by thin-layer chromatography (TLC; ethyl acetate=n-hexane 3=1), the product was precipitated by addition of 10 ml of water. The precipitate was filtered off, washed with water, and then recrystallized from acetone. In the case of aromatic aldehyde, precipitate after filtration was loaded on column chromatography with 20percent ethyl acetate?hexane as an eluent system to furnish the product.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Diaminomaleonitrile, its application will become more common.
