Document Type and Number:
WIPO Patent Application WO/2023/124970
Kind Code:
A1
Abstract:
Disclosed are a cyclic 1,3-diketodiimine compound with a symmetrical structure, a synthesis method and use thereof. The compound has a structure represented by the following general formula (III), (II), or (III): wherein R1-R5 are each independently selected from the group consisting of H, halogen, and saturated C1-C10 alkyl, and n = 0, 1, or 2. The cyclic 1,3-diketodiimine compound with a symmetrical structure can be applied to solvent dehydration and dealcoholization, and possesses a practicable and simple synthesis method.
