Synthesis, Properties, and Light Fastness of Diaminomaleimide and Some of its Derivatives

Reaction of ammonia with dichloromaleimide (3) yields the aminomaleimides 1 and 4, 2,3-dichloromaleamide (6), and 2,3-diaminofumaramide (2) depending on solvent, temperature, and pressure.The reactivity of the eneamino groups in 1 and 4 are remarkably different, 1 reacts like an amine while 4 resembles an amide.Interpretation of the ultraviolett and fluorescence spectra shows that 1, 4, and the acyl derivatives 13 - 15 can be classified as meropolar dyes.Light fastness values and fluorescence yields show a reverse correlation by change of solvent.Photochemical decomposition and fluorescence show a reactivity-selectivity correlation by variation of substituents at the double bond.
