This paper summarizes the research progress of dielectric elastomer (DE) and its composite materials, including the introduction of materials, theoretical research development, and typical applications. First of all, the DE composite materials are introduced. Then, the theoretical research development of DEs is summarized. Finally, some applications as well as research prospects about DEs are listed. 相似文献
The palladium‐catalyzed decarboxylative asymmetric allylic alkylation (DAAA) is comprehensively reviewed, from its original development to recent advances in terms of substrate scope, reactivity, regio‐ and enantioselectivity. The current understanding of the mechanistic details, based on a combination of experimental and computational studies, is described. Selected examples of the application of this asymmetric synthetic methodology in natural product synthesis are given. The exploration of Pd‐catalyzed decarboxylative asymmetric catalysis, in particular, the related interceptive decarboxylative asymmetric allylic alkylation, has become a focus in recent years and this is also summarized.
