The Heck arylation of maleic anhydrides using arenediazonium tetrafluoroborates was investigated. Symmetrical and unsymmetrical 3,4-diarylmaleic anhydrides, some of them showing interesting fluorescent properties, were prepared in one or two steps from ch

Diarylmaleic anhydride derivatives containing benzene (BPMA), thiophene (BTMA) and indole (BIMA) exhibit diverse and distinct fluorescence: aggregation-caused quenching (ACQ) of red emission of BIMA, blue aggregation-induced emission (AIE) of BPMA, and green dual-state emission (DSE) of BTMA in both solution and the solid state. Theoretical calculation and crystal structure analysis indicate that intramolecular and intermolecular interactions are responsible for their different emission behavior. A series of DSE-active molecules with full-color emission could be developed for the first time, through modification of the structures of BPMA and BIMA. Interestingly, BTMA and BPMA display multi-stimuli-responsive luminescence with a high-contrast (Δλem > 100 nm) and an unusual photochromic phenomenon in dichloromethane, which were utilized to construct rewritable data storage and mimic molecular logic operation (4-to-2 encoder and 1?:?2 demultiplexer), respectively.

α-Halo hydroxamic acids were used in the synthesis of N-methoxyindolinones, symmetric and dissymmetric N-methoxymaleimides in good yields. The hydrolysis of N-methoxymaleimides constitues a new and good route to maleic anhydrides.

α-Halohydrazides react with 2-aminopyridine to give symmetrically substituted N-aminomaleimides.We have shown that this reaction proceeds through the formation of 4-hydroxyimidazopyridines.This result opens a new route to dissymetrically substituted N-aminomaleimides.The hydrolysis of N-aminomaleimides is a grood route to substituted maleic anhydrides.
