The reaction exhibits good functional group tolerance, including amino, carboxylic acid, boronic ester, and heteroaromatic rings. Gram-scale synthesis (79% yield) and derivatization to pharmaceutically relevant compounds demonstrate the practicality of this method. Mechanistic studies reveal that the transformation proceeds through amide and thioamide intermediates. The protocol features inexpensive reagents, no transition metals, air compatibility, and simple operation.Aromatic nitriles are fundamental building blocks in organic synthesis and serve as key structural motifs in numerous pharmaceuticals, agrochemicals, natural products and functional materials (Fig. 1). [1][2][3] The nitrile group can be readily transformed into a variety of other functional groups, making nitriles versatile synthetic intermediates.

In this review, we summarize the recently adopted fluorescent analysis events with organic probes. The detection of nerve agents is first introduced based on nitrogen activation, hydroxide-activation, cyclization, and other mechanisms. The blister agent detection is concluded in three aspects: thiocarbonyl site recognition, thiol site recognition, and other principles. The applications of fluorescence detection systems toward chemical warfare agents or simulants are by turn-on and ratio metric tactics. In the end, this review highlights the challenges and future trend of chemical warfare agent’s responsive organic probes.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"23 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374955","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}
