The organic molecules selectively adsorb on the zinc surface, where they effectively capture protons, buffer the local pH environment, and inhibit active water molecules. This mechanism suppresses parasitic side reactions and promotes uniform zinc deposition. As a result, the Zn||Zn symmetric cell achieved stable cycling performance for over 860 hours at a 0.5 mA cm -2 and over 730 hours at 1 mA cm -2 . Furthermore, the full cell with NH 4 V 4 O 10 cathode retained 84.2% of its capacity after 2000 cycles.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"2 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method exploits the lone pair of electrons on the pyrazole ring of 1 as a traceless directing group, enabling ortho C–H activation followed by Michael addition and cyclization, circumventing the traditional need for pre-functionalization steps such as halogenation or alkylation. Notably, PZQZLs (4) bearing seven-membered rings were unexpectedly formed in certain cases. Furthermore, derivatives (3) were readily transformed into pyrazolo[1,5-a]quinazoline-5-carboxamides (5) upon heating with K₃PO₄ in DMSO. This work provides a representative example of utilizing 5-amino-1-aryl-pyrazoles (1) as C5 synthons. It lays the groundwork for future strategies to access diverse cyclic structures via [5 + 1], [5 + 2], and other cycloaddition reactions. These strategies can also be applied to the combinatorial and parallel synthesis of functionalized pyrazolines.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"23 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
