Imide synthesis
Witryna1 lip 2024 · Reaction with primary amines to form imines. The reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation. WitrynaWe have established a new ionothermal synthesis route for imide-linked COFs, with which we were able to synthesize two crystalline and porous COFs (TAPB-PTCDA- …
